The rood habits of arctic foxes denning on both lo~middottland

tundra and sea cliff habitats on St Lawrence Island Alaska

trere studied from 9 June to 23 August 1968 Analyses of

1555 scats and the remains of dozens of prey revealed that

in general the composition or the diet reflected re~ional

differences in the availability of prey species

Based on the frequency of occurrence of their remains

in seats about 90~ of the diet of foxes denning on lowlandmiddot

tundra consisted or small mammals Of the five species or

small mammals on the island the tundra vole was by far the

most frequently represented in scats The remains of birds

primarily eider and oldsquaw ducks and emperor geese

occurred in 20-30 or the seats collected on the tundra

A high frequency of occurrence of avian remains (80shy

100) was noted in scats collected on cliffs adjacent to

the sea reflecting the proximity of thousands or nesting

seabirds Species were taken in proportion to the accesshy

sibility of their nesting habitat Crested and parakeet

auklets sustained the greatest de2ree of predation while

horned and tufted puffins were taken in moderate numbers

imiddoturres 1 pigeon guillemots 1 pelagic cormorants bull and larids

were taken only rarely

~nough readtly available marine ~ammal carrion and

marine invertebrates were little used

INTRODUCTOtr

St Lawrence Island 1 Alaska lies in the northern part

of the Bering Sea 1 a region chara~~erized br leaden skies

and gale-force winds Approximately 600 Yupik Eskimos 11 ve

on the island 1 with the population almost equally d~vided

between ~~= percenent Villages 1 Gambell and Savoon~a The

furs of the arctic fox (Alopex la~opus) provide an imporshy

tant source of income for many of these people

According to Chesemore (1967) 1 the islands in the

Bering Sea produce the highest catch or foxes per unit area

of any geographical region of Alaska and st Lawrence

Island account~ for the greatest proportion of the catch on

these islands Catches of 50 and 100 foxes per trapper are

not uncommon on St Lawrence Island (Ru~~a~bull 1960)

Initiation of the present study was prompted by the

lack of basic information needed for sound management of the

arctic fox population en St Lawrence Island A unique

ecological situation exiGts on this island in that both tunshy

dra and coastal biotopes are present 1 each supporting

abundant prey popllations during the swmner lmiddotiy primary

obje~tive was to d=te~~ine the food habits of foxesmiddotdenning

in areas representative of the two major biotopes See~nd-

I From studies on its morphological characters Pausch I

I (1953a) concluded that tne arctic fox is a single hi~hly

variable species or circumpolar distribution It became

apparent to me 1 after a perusal of tile literature 1 that

the arctic fox is remarkably versatile in its food habits

as well The list or roods utilized by this animal includes

a wide variety of plant and a~imal organisms both ~arine

atd terresttbullial in origin The rrreatest variability in

diet occurs durin~ winter when these animals roam far ~nd

wide obtaining nourishmentfrom ~variety of sources Durshy

ing the breedin~ ~eriod the ~exes are linked to certain bioshy

topes and hence dependent en a foo1 supply of relat1~ely

limited variety (Vibe 1 1967) Braestrup (1941) 1 1n his

)1 treatise on the arctic fox in Creenland 1 indicates that an

ecological differentiation exists between foxes dependent

II i

on lemmings (Lemmus and Dicrostonyx) and those dependent on

products of the sea He termed the former type lemmin~

foxes and the latter coastv foxes In a more recent conshy

sideration of rox populations 1n the arctic Vibe (1967)

supported Braestrups views adding that the white color

phase is characteristic of lemmin~ foxes while the blue

color phase is predominant 1n coast foxes

noted the primacy of lemmings in the foxs summer diet

Shibanoff (1951) described a similar situation on the tunshy

dra of northern Russia On St Lawrence Island the tundra

vole (lticrotus oeconomus) rather than the lemmin~ is the

predominant microtine rodent on the islands tundra

DESCRIPTION 0 THE STUD AREA

St Lawr-cnce-Idand (Fig 1) is about 100 miles ( 160

km) long and 10 to lO miles ( 16 to E4 len) wide and lies in

the Bering Sea about 200 miles (320 km) south or Bering

Strait Fa~ and Cade _1959) have reviewed the major ecoshy

logical considerations including pmiddotysioyraphy bull cliJTOate 1 and

vegetation The island is primarily or volcanic origin

mountain ranges occupying about one-fourth of ~ts 2 1 000

square mile (5180 sq km) surface area About two-thirds

of the interior land is low 1 rolling tundra dotted with

lakes The flora is characteristic of the circumpolar tunshy

dra biome the almost complete laclt of arborescent forms or ll

shrubby species beinK the prima~y distinction between its llil

vegetation and that of the adjacent mainlands

My assistant and I spent the periods from 9 to 27 July Ill and from 17 to 23 Au~ust on the Putgut Plateau study area

(Fig 2) The sotthern rim or this formation is at an

elevation of 100 feet (305 km) above sea level and is

oriented 1n a general east-west direction about 1 mile

north or the coast The southbullfacing slope or this ancient

wave-cut terrace rises 9 to 15 m above the tundra To the

north and south of it lie areas of ~ently slopin~ tundra

and pound2 are typical (tltay and Cade 1959) Numerous small

streams drain the plateau their valleys are conspicuous

features of the plateau rim The rJmald river valleya are

characterized by dry rocky ground ccvered with lichens

scattered herbs and some ~and Dryas

The period from 28 July to 16 Jlugust was spent on the

sea cliff study area located on the southwestern coast n

the vicinity of Boxer Bay (Fig 3) Here on the southern

limits of the Poovoot Range are located precipitous slopes

ranging in height trom 50 to more than 11 000 feet (15 to

more than 305m) ay and Cade (1959) recoFnized two ~ajor

types or sea cliffs on St Lawrence Island One ty~e they

termed rock-pile11 cliffs 1

characterized by r-reat heaps and jumbles of boulders rangnp in size from a few cubic 40eet to sevelil hundred cubic feet and occasionally tall pinnacles or columnar shafts Jut up from the con 40usion of smaller boulders These clif~s are particularly disshytinguished by the absence of sheer rocky escar~ments though they are in some nstances adjacent to them

Ihe portion or the cliff study area to the ~fest of Boxer

Bay is principally of this type The other type of cliff

designated by Fay and Cade is the bullsheer-walln typP 1

characterized by high escarpments rangin~ in hei~ht from about 200 to nearly 11 000 reet These precishypices frequently drop directly into the sea with little or no ~ntervening beach but in most instances the sheer-~falls are interrupted at intervals by rockshypile cliffs The most abundant and characteristic plant of the sheer-wall cliffs is Sedum roseum 1 which occurs principally on the upper le~

The cliffs on the east side of Boxer Bay are representative

of is type Th~ c~s~1netive associatio~ cf birds round

on etch type of cliff ~Cre described by Fay and Cade and

ill be considered in the following section

Another distinction betweampa these habitats is the

character of the areas inland from them The uplands adJashy

cent to the rock-pile cliffs are al~ost entirely rocky

barrens while those adjacent to the shee~-wall cliffs su~shy

port considerable areas of wet and ~esic tundra This is

due primarily to the relatively steep~r slopes and the

diterent substrata-round in the uplands adjacent to the

rock-pile cliffs For comparative purposes I have treated

the data f~om these a~eas separately

The Boxer River Valley ~rovided yet another habitat

near the cliffs For a distance of one mile north or the

mouth of this river the floor of the valley is tbout one

mile in width relatively flat and characterized by wet

tundra The surrounding area is almost entirely bRrren

uplands although some mesic tundra is found to the north in

the Boxer and Wanmayee river valleys

METHODS

Primary sources or data on the summer d~et or the arcshy

tic fox were scats anq rood remains collected at den sites

obtained some additional information by observing the

hunting behavior or roxez although rrequent ro~ reduced the

effectivene3s of this technique~

As originally planned1 scats and food remains were to

be collected at each de~ sita at intervals of two weeks so

that changes in the summer diet related to environmental

changes could be detected ThE gneral location or several

dens had been obtainea fro~ Francis H ~ay (viva voce) ~nd -

from several people in the villa~e of G~Tbell Ho~ever 1

the inconspicuous nature middotor fox dens o~ the plateau~ my

lack or fami+iarity with the study area and the necessity

or conducting field investigations on root made the initial

location or dens more difficult than expected These raeshy

tors and the comparatively short period or time I was able

to spend in the clirr study area resulted in the data bin~

more heterogeneous 1 with respect to time and number of colshy

lections per den than was desired

Every scat round was collected Those not associated

with a den were analyzed as random collections ea others

were analyzed according ~o den number Gate 1 and study area

Scats and rocd remains were placed in indiVidual paper bags

10

_j

11

Since the foxes on this island frequently harbor adults of

the cestode Echinococcus multilocularis (Rausch 1967) 1 the

causative agent of alveolar hydatid disease in man scats

were handled with forceps in the field and analyzed only

after being autoelaved at the Arctic Health Research Center

in College Alaska

Scats were composed primarily of indigestible matter

including hair claws bone teeth 1 reathers ve~etation 1

and soil The scats were pulled apart and their content~

identified by comparison with study skins and skeletons of

birds and mammals collected on the island fmiddot~aiUal remains

were identified using color and texture or ~ur and dental

skeletal 1 and claw characteristics Avian remains in seats

were principally body feathers and were classified usin~

the size 1 color 1 and shape of quills It was ahrays 90ssishy

ble to identifY mammal remains at the speci-s level out

avian remains could usually be identified with cert~int~

only to the family level

From a study in which captive red ~axes (Vuloes vulpes)

lrere fed known quantities or prey and their fecal emissions

studied Scott (1941) concluded that frequency of occurrence

provided the best estimate or the relative importance of

prey species He round that in ~eneral fecal passages

are produced approximately in direct proportion to the

quantity of food consumed ~rom a similar study Lockie

(1959) concluded that percentage wei~ht is the most accushy

12

rate way or interpreting the results o~ recal analysis

IFor the purposes or the present study I employed the freshyI

quency of occurrence method since the volume of material

precluded the use or the latter method To show the relashy

tive frequencies of occurrence or the species of small I

mammals and families or birds represented 1n scatmiddots I have

presented the data with these segments delineated However

to obtain an indication of the relative importance or the

two major groups (birds and small mammals) 1n the diet a

different treatment was required As noted above small

mammals were easily identified to species while bird reshy

mains could in most oases be identified only to the family

level For this reason as well as the fact that due to

their small size a relatively ~reater variety of small

mammals can be ingested in a short period of time by a fox

small mammals are likely to score a greater number or

occurrences in a scat than are birds Because o~ this I

have also presented the data in the ~~uped orm sugshy

gested by Scott (1941) By this method each group c~n

score no more than orle occurrence in a scat These compushy

tations avoid overemphasizing the importance or small

mammals and underemphasizing the impQrtance or birds in the

foxs diet

I collected forty species of birds and the five species

or small mammals fowtd on St Lawrence Island and prepared

their skins and skeletons as reference material for the

L

13

analysis or scats and food remains

~~enever possible 1 food remaL~s as o~posed to scats 1

were analyzed in the field This treatment was especially

effective at dens located in alcid nestin~ colonies where

there was a considerable volume or material 1 primarily

alcid remains and an accurate and rapid determination o~

species compos1tion was possible The data on food remains

for each den indicate the minimum number of individuals of

each species representen in the remains Thou~h they are a

qualitative ind1cation of species ta_~en by roxes 1 these

data are not a quantitative sample of diet for they are

undoubtedly biased in favor of lar~e birds which are unshy

-- lilcely to be completely consumed surther they are not an

accurate indication or the number or individuals consumed 1

for prey are not ah1ays consumed at the den Some remains

could have been inside the den others could have been

scattered elsewhere by larids (B~dard 1 1967) and other

scavengers Host of th scats anci rood remains that I found were

fresh and evidently had accumulated in the spring atld sumshy

mer of 1968 For this reason 1 my data are considered to be

indicative of the summer diet only The late summer colshy

lections at dens hcldL~g litters or pups provide a good

record or pups in adolescence as Lund (1962) sug~ests

Some of the den~ that I visited probably had produced lit shy

ters uf pups during the previous summer but the small numshy

ber of old scats coll~cted there early 1n the su~mer of

1968 sug~ests that many of those that accumulated earlier

had disapp~ared during the winter months aj vva voce)

found scats in the stomachs of St La11rrence Island foxes

trapped in the winter months and he reports that 1 in late

lrinter and sprinp rood r~sources ae so limited that any

available organic material is likely to be in~ested by

foxes

The variation amon~ groups of scats rrom the dfrerent

habitats in the frequency of occurrence or small ~ammals 1

birds and egg shells was statistically evaluated middotzth a

Chi-square testbull The overall rrequency of occurrence of

each of the above food items 1n scats without regardmiddot to

study areas bull was considered to be the expected frequency

The frequency of occurrence observed in scats collected on

each study area was then tested against the appropriate

expected frequency to determine any statistically signifishy

cant difference The statistical si~ificance of the reshy

sults will be discussed in conjunction with the data from

each habitata

PREY POPULATIONS--PLATEAU STUDY AREA

Of the three microtine rodents endemic to the 1sland 1

~nly the tundra vole (M1cr~tus_nP-c~nornu5) is abundant

(Rausch l953a Fay and Cade 1 1959) Burrows a~d runways

or this animal were commonly seen on the tundra above and

below the plateau rim Fay and Cade (1959) indicate that

the tundra vole population undergoes periodic fluctuations

but without the am~litude observed in lemmin~ ~opulations

A snap-trap census conducted during late Au~ust by Francis

H Pay of the Arctic Health Research Center indicated that

the tundra vole population was moderately hi~h compared to

previous year~ Little is known of the status or the redshy

backed vole (Clethrionomys rutilus) or the collared lemmin~

(Dicrostonyx torguatus) except that both are relatively

uncommon (Rausch 1 l953a) In other areas of Alaska the red-

backed vole has been associated primarily ltith areas there

overhead cover is available (Bee and Hall 1 1956 Pruitt 1

1967) Apparently 1 this habitat preference is also charshy

acteristic of the red-backed vole on St Lawrence Island as

they are round in the vicinity of boulder fields (Fay 1 viva

voce) Rausch (1953a) indica~es that the tundra shrew

(~ tundrensis) is uncommon only one las caupht in the

small mammal census durinF the ~resent study The arctic

ptbullould squirrel (Citellus middotuldulatus) is common on the wellshy

drained slopes of the plateau while nearly absent rrom the

surrounding tet tundra

The only passerine birds I saw were the lapland lon~shy

spur _(Calcarius laponieus) and the snow bunting (Plectroshy

nhenax nivalis) Longspurs were typieal of the ~sic tunshy

dra while snow buntings were characteristic of rocky areas

on the plateau rim I found several nests or the lon~spur

in late June and early July 1 and newly fledged younp of

this species wer-e occasionally seen in early July

Shorebirds were abundant in this area 1 the most common

being dunlins (Erolia alpina) 1 roek sandpipers (~ ~tilocshy

~)1 and red phalaropes (Pha~aropus fulicarus) middotPresent

though less common were the northern phalarope- (Lobipes

lobatus) 1 western sandpiper (Ereunetes ~) 1 long-billed

dowitcher (Limnodromur middotscolopaceus) 1 ruddy turnstone

Arenaria interpres) 1 and golden plover (Pluvialls dominic)

Nests of species in the first group were commonly found in

June

Fay (1961) estimates the summerin population or waterbull

fowl on this island to be about 9 1 000 nestinF and more than

25 1 000 non-breedin~ ducks geese 1 and swans Both breeding

and non-breeding segments of the waterrowl population were

represented on the plateau study area or the rour species

of eiders present the most abundant was the common eider

(Somateriamiddot ~llissima) I found ne6ts of this species near

the beach 1n late June though most oceu~red on several small

RESULTS

A total of 2~ dens was fnund during the study 15 or

these were located ~n the plateau study area (Pi[ 2) and

nine in the Boxer Bay area (P~g 3)

St Lawrence Island is known for its relatively high

population density or oxes and during the ield investtSshy

tion sightings tere o almost daily occurrence The many

foxes that I observed exhibited a variety or responses to

my presence ranging from ind~rrerence and close a~proach - shy

to avoidance at a distancemiddotof several hundred meters

Almost without exception however the foxes became quite

vocal when I approached them

Fox pups were irst seen outside of a den on B July

at den 1~ and sightin~s here and elsewhere increased as the

summer progressed Thour~ first seen only nep~ the den

entrance by mid-August pups were observed traveling up to

100 m from the den in the course of play activities This

increase in pup activi~y is reflected in the sudden appearshy

ance of large numbers or scats at these dens after mid-Jul7

Pups were often seen during relatively fair weather and durbull

ing late afternoon and evenin~

~11th the following exceptions lll or the foxes that I

observed on the island were or the white color phase The

one adult blue phase arctic fox seen durin~ the surr~er was

one parent of a litter o~ at least five pups at den 22

Three c~ these pups were blue phase and t~ro were tlhite

observed at den 13 on 21 August tlere of the blue color

phase The entire coat of both pup ad ad11lt blue foxes

was sooty brotm to almost black in color In summer the

adult IThite foxmiddot is dark brown on the face neck 1 back 1 legs 1

and the dorsal surface of the tail and ~reyish white on

the sides and underparts (Pigs 9 and 12) The ~rhite phase

has been described-by Chesemore (1~70)

I collected ad analyzed a total of 1 1 555 scats and

the remains of dozens of birds The results from each den

with a brief description of the den site the activity o~

foxes in the vicinity and the general condition of food

remains are presented in the following pa~es

Plateau Study Area

Five dens on the plateau had litters of pups at some

time during the summer thou~h in one and possibly ttoro

cases pups were tcved from one den to another hese dens 1

with one exception were relatibullrely extensive in construcshy

tion having from five to 13 entrances Only cne den was

discovered in a wet tundra situation though others could

24

have been present This den (den 9) was on a 2 rn elevation

alon~ a small stream All other dens in the plateau area

ere assc-ciated with either mesic tundra or rocky barrens

on the slopes or the plateau and river valleys (Fig 5) -middot

The burrowing_ or ground squirrels appeared to exert a

direct influence in deter-1lininr the location of dens The

burrows of these ani~als were almost always nresent amon~

those or foxes ~nd three of the si~gle entrance fox dens

that I excavated in late August fere enlarped round sq_uirshy

rel burrows the upper 1 to 2 ~ bein~ used by foxes The

plant comrumities around dens lere noticeably altered in

that the dry tundra community was replaced by relatively

lush stands of grasses and sed~es This chanre is due ~ri-

~arily to disturbance and the addition of or~anic compounds

to the soil

Iii the middle of June 1 durine the spring thalmiddotr I found

three caches or small mammal~ ~1nn= the plateau rin The

first c~che found on 13 June at den 1 1 contained five

tundra voles (Fig 6) On 16 June another cache ras found

at den 4 containing 27 tundra voles ~ red-backed vole 1 and

a collared lemmin~ The third cache containing 16 tundra

voles and a collared lemminp 1 was found 50 m from den 1 on

18 June or the tundra voles in these caches 736 were i

males The five voles in den 1 ere piled 50 em inside the

Den 14 had 11 entrances and seeled to be a well used

scats and remains found on the first visit (Table 7) At

least four pups were seen enterin~ this den on 9 July and

two adult foxes 1 includin~ a lactatin~ fernale 1 were seen at

that time The great number of scats that accumulated there

during the li2 days beheen the first and second collections

and similar accumulations at dens 11 1 14 1 and 15 are undoubtshy

maxillae and portions of the appendicular skeleton

Den 15 was the only den round ~n the plateau associashy

ted with large boulders These boulders were in two formashy

tions about 50 m apart Fach formation had three entrances

This site was visited early in the summer but evidence o

foxes using it was not ound until 22 Au~ust 1 when I saw

six pups All food remains and seats found at that time

appeared to be fresh (Table 8) Each bird was represented

by a sternum one or both win~s 1 o~her bones 1 an1 ~eathers

The condition of some of the pri~ary feathers from the

reese indicated that at least three o these bircls lrere

completing a molt when killed

The combined results or analyses or scats and rood

remains from all dens in the plateau study area are shcwrn

in Table 17 The scats collected on the plate~u indicate

that the summer diet of young foxes in this area is comshy

posed primarily or small mammals and that the tundra vole

is the predominant prey The frequency of occurrence of

this species was consistently 95 or more in the collection

or scats deposited jy fox pups The overall fr-aquency of

occurrence for this vole is slightly over 90~ Of the

remaining small ma~~al species the tundra shrew occurred

than 10~ of the seats I considered the presence of fox

hair vegetation or soil in seats to be due to accidental

ingestion The occurrence of marine carrion (pinnipedsmiddotand

boulders (Pigs 10 and lll tthile only one den on the plateau

was associated with a large rock formation The number or

entrances to the dens in the cliff area varied from three

to eight At least four of these dens contained litters of

August a fox carry1n~ a crested auklet was seen The bir1

was dropped and upon examination proved to be freshly killed

b a bite throu~h the neck On 14 ftuust a female fox

carrying a parakeet auklet returned to its den after an

absence of 40 minutes This bird was freshly taken and

killed in the same manner as the crested auklet On the

same day a fox as obse1bullved stalkinp a lroup of horned

puffins and a few minutes later a crested auklet In both

instances this fox crawled to within 3 m of its intended

prey but then abandoned the stalk probably because of its

awareness of the observers presence Neither their moveshy

ment nor the vocalization of fo~eg eaused any widespread

alarm among the ne~ting alc1ds

Den 20 was located under a larre overhan~ing rock on

the rim o~ a ste~p slope a rew hundred meters east of J Siteeluk Bay Though I observed adult foxes in the vicinity

the quantity of scats and food remains found was relatively

meager~ middottnciicating intermittent use or at least that no ~u~s

leeted appeaIed to be from birds taken in recent months

The great p-reponderance of parakeet auklets in the rood

remains (Table 12 is striking and not readily attributable

to a local abundance of this species In addition the food

remains collected at this den and at den lB are the only

remains in which the least au~at is represented Although

none or the major nesting colonies or this bird are located

in the study area the species is present in numbers co~arshy

DISCUSSION

bullrne arctc foxs preference for denninr~ in elevated 1

well-drained soils has been noted by several authors

Tsetsevins-1(1940) found most or t~e arctic fox dens on

the Yamal Peninsula to be situated on ~he banks or rivers

and strtdJils In the lower reaches o the Kara and Sibirshy

chayalka R1vers 1n Russia Danilov ( 1958) found 37 o 41

dens built-on the main valley sides indicatin~ a marked

tendency to use elevated locations Danilov also demonshy

strated that areas having a comparatively deep active frost

layer and high soil temperatures are favored by foxes for

denning Chesemore (1967) described similar characteristics

in arctic A1aska 1 as has -tee)herson (1969) in arltic Canada

The rocky sloping ground along the rim and river

valleys or the Putgut Plateau is relatively trell drained and middot

could be expected to have a dee)er active rrost layer than

the surrounding areas of comparatively level tundra The

above eondi t1ons cause the soil on middothese slopes to l oelashy

tiv~ly drier and more stable and thus account for the foxs

preference for denning in these areas In addition ground

squirrels favor similar soil conditions for burrowing and

their burrOlS are often enlarfed and used by foxes Pecal

deposits of ground SQu1rrels were commonly found in entrances

to fox dens and on several occasions ground squirrels were

58

59

seen in dens known to have been used by foxes only a few

days previously Ths apparently close association or

predator and prey deserves further study Yacpherson (1969)

reports that foxes often utilize dens throu~hout the winter

and various trappers on St Lawrence Island reported similar

observations The use or a elevated location such as the

plateau rim for denning is thus a further advanta~e in that

such areas are kept relatively rree or snow by wind 1 allowshy

ing easy access to dens in winter

In the more rocky habitat around Boxer Bay the ~~~~~~n

arrangement and extent of each den site depends on the posishy

tion or large boulders Tnis situation resembles that found

on the Commander Islands by Barabash-Nikiforov -(1933)

The influence that territoriallsm has in deter~inin~

the density of occupied dens and the home ran~ of roxes is

not known but it may well be an important factor One

instance or territorial behavior was observed in mid-June

I II on the plateau This involved one fox s~oradically chasing II

another tor a distance cr about 200 m alonE the platean rim

Both foxes vocalized frequently durin~ the 10-minute chase

Bedard (1967) noted that the periphery or the Kon~kok basin

a large cirque located several kilometers west of Boxer Bay

was divided among five or six foxes and he observed terrishy

torial clashes among them

The caches round during the present study indicate

that the foxes inhabiting lowland areas may take advantage

I

60

or a temporary increase in the vulnerability or m1crot1ne

rodents due to loss of snow cover and concurrent flood1n~

or burrO)TS during the SJ)ring thawbull The fact that these

caches ~rere located well away from the more extensive dens

where pups ~ere round may indicate that they were delibershy

ately established where pups could not interfere with them

Though no caches were round in the Boxer Bay study

area middotr Charles Slwooko an elderly resident or the island

reported that he and other men had found caches of nlttle

auklets and other birds in this area in ~revious years

Considering the overwhelming abundance or alcids it seems

that gathering a surplus of these birds would be quite easy

for the foites

There is evidence indicating that the ~oxes on the

island depend on prey cached in the summer rnonths for part

or their winter diet The scarcity or prey species in the

~inter months is as striking as the abundance in summer

Except for a few ravens terrestri~l birds are absent from

the islandin winter though marit~me birds primarily oldshy

squaw and eider ducks are round offshore in considerable

numbers ~round squirrels~ or course hibernate durin~ the

winter and other swAll mammals are largely unavailable beshy

cause of snow cover Nevertheless the stomachs of a conshy

siderable number of foxes trapped in winter contained

remains or birds that do not winter in this re~ion as well

as an abundance or small mammals or limited availability

61

(Fay unpublished data) Further research is needed to

adequately describe the caching activities or the foxes on

St~ middotmiddot-ence Island Though evidence is in most cases

fragmentary 1 there seems to bE a cansensus amo1 investishy

gators that have worked in other regions that the arctic

fox often caches various foeti items tn summer when food is

most plentiful (Fielden 1877 Bedcat~d 1 1902 OsYood l bullbull 1913 Gibson 1922 Seton1 1929 Freuchen 1935 Dubrovskii 1

1937 Braestrup 1941 Soper 1944 Tuck 1 1960 andBarry

1967)

~ne frequency of occUrrence of small mammal remains in

scats collected on the plateau in summer indicates that

these animals are thR predominant item in the diet of foxes

inhabiting the islands vast areas of tundra Similar

results have been obtained in comparable habitats by

8raestrup (1941) Elton (1942) 1 Mineyev (1946) Pitelka

bull (1955) 1 Macpherson ( 1969) 1 and Chesemore ( 1967) From

his observations on St Lawrence Island 1 Rausch (1958)

stated that voles are an important food resource for youn~

foxes while 1n the den This view is substantiated by the

results from the plateau ~~d Boxer River valley study areas

The litters reared in dens near the cliffs however were

dependent primarily on alcids ror food

The frequencies or occurrence of the three microtine

rodents the tundra shrew and the ~round squirrel correshy

spond in a general way to the relative population levels

62

of these species However as EnFlund (1965) has su~~sted1

differences in catchability may exist among the species an~

the fox rna sholr a preference for cermiddottain species The

tundr=t vclcs habit of living mainly in the o~en tunri~ mP-Y

render itmore vulnerable than for instance the red-back~d

vole which is found in rocky habitats From studies done on

the food habits of the red fox Errin~ton (1935)middots~ott

(1943) Scott and Klimstra (1955) Lockie (1957) 1 and Lund

(196) havE suggested that this species has a ~re rerence

for - -ctus over other small middotllammals The extremely low

occurrence of tundra shrews in scats may also be influenced

by the predilection of the foxes for voles Scott and

Klimstra (1955) and Lund (1962) lave sholn tMt insecti-

vores are killed but often lert uneate~ by the red rox

or the avi~~ re~ains identified in scats from the plashy

teau members or the Order Anseriformes were represented

most frequen~ly The food remains indicated that the prinshy

cipal species involved were the oldsquaw 1 common ei1er and

emperor goose Tne condition of some of the remains of the

latter species indicated that these individuals were moltshy

ing and hence flightless fhen captured Residents o the

isl~~d reported other cases of foxes preyin~ on molting

geese and it is likely that a major pertion of the ~eese

taken by foxes are in this condition ~ineyev (19~6) debull

scribes a similar situation on Wranvel Island

The arctic fox has been shown to be a hi~hly Qfficient

63

predator on the eggs and young of waterfolrl (Lewis 1923

and 1942 Kenyon 1961 Ryder 1967 Barry 1967) In a

study--or toJaterf~wl nestinsr on the Anderson River Delta

~Jorthwest Territories bull Barry ( 1967) found that s~ecies

larger than Pacific brant (Branta bernicla niaricans) ere

ca~able of driving foxes away fro~ nests while brant and

smaller birds could not do so effeetivelt and thus required

island habitat for successful nestinv Barry regularly

observed a pair of whistling swans harassin~ nearby foxes

It appears that this general princi~le ~~ vp~~ative on St

Lawr~nce Island as well since nestin~ eiders and smaller

waterfowl favor island locations while lar~er birds notably

the whistling swan and sandhill crane 1 nest on the inland

tundra on the ~lateau study area nests o~ the latter two

species weremiddot found within a few hundred meters of occupied

fox dens

The occurrence of ~asserines and shorebirds in seats

and remains was relatively low in all of the habitats

studied Though the roxmiddotis capable or eapturinY these

birds (Jones viva voce) and they are abundant it appears

that other prey are more easily obtained and the foxes ca~shy

ture small birds only occasionally

It is probable that the alcids identified in the bird

remains collected on the plateau were picked up as carrion

on the beach Murres and other cliff nesting birds are

often killed by falling rocks and there is sometimes conshy

64

siderable mortality among youn~ alcids 1 especially when

they are leavin~ the nesting colonies in lar~e nw~bers durshy

ing late summer and fall (B~dard 1967) The carcasses or

these birds may wash ashore at distant beaches Thus 1 each

alcid nesting colony in the arctic is 1 directly or indirectly

impo~tant to foxes as Tuek (1960) has su~~sted

-Descriptions of the arctic foxs predatory habits in

a1cid nesting ereas nmiddotmiddot ornmon middotin the lite~ature but vary

widely with the species of alcid and the type of nesting

habitat involved In ~neral the arctic fox has been

shown to be the primary factor governin~ the nest location

of seabirds (Turner 1886 Nelson 1887 Manniche 1 191

Kirpichnikov 1937 Bertram and Lack 1938 B1middotaestrup 1 1941

IbulllcEwen 1958 Fayand Cade 1959 Tuck 1 1960) Alcids

nesting under rock-piles thus require interstices of a size

permitting their antry while offering ~~otection against

foxes and other prenators In like manner puffins and

guillemots utli~e burrows or crevices and the murres 1 corshy

norants1 and larids are restricted to the most precipitous

cliff~ due to their hab~t of nesting above gr~d

Though the vulnerability of the various nestiny seashy

birds needs to be more fully documented some general stateshy

ments can be made concerning this aspect with relation to

the Boxer Bay study area Bed~rd (1967) has described the

ecological relationships of the three species of auklets

found on the island The majority of nesting least and

65

crested auklets are concentrated in a few well-defined

colonies middot1hereas parakeet auklets ale more widely distri shy

buted along the cliffs but occur at lower densities than the

least and crested auklets The latter two species and

especially the crested auklet 1 were pre~ent 1n conside~able

n~rnbars we~t of Boxer Bay even though the study area did not

encompass any of the major nesting ~1middot-a A few creted

auklets iere seen east or Boxer Bay but least auklets middoture

rare Parakeet auklets were ab~~dant on the eastern cliffs

but only moderately so on the cli~fs to the west of Boxer

Bay

The least a~d crested auklets arc undoubtedly the most

vulnerable of the-cliff-nestin~ birds The vulnerability

of the former species hoofever 1 is not reflected in the

rood remainz The presence of entire win~s of the least

auklet in some scats indicates that due to its small size

the entire carcass o this s~ecies may be consumed by the

fox From his observations of food remains in the lar~e

auklet colonies on the island Bedard (1967) concluded that

the crested auklet is the main object of fox predation in

middotthese areas Tnis view is supported by the results of my

studj In terms of numbers and probably in terms of bioshy

mass the crested auklet sustains a higher level of predashy

tion th~~ any other cliff nesting bird

The characteristically precipitous habitat of the

parake~t auklet would appear to render it ~uch less susshy

66

ceptible to predation than the other auklets Nevertheless

the food remans indicate that this bird is taken 1n conbull

siderable numbers The overwhelming preponderance of parashy

keet-auklet remains at den 23 could be attributed 1n part

to a highly efficient method of capturin~ these birds used

by the foxes inhabiting the site or perhaps to a predomishy

nanceof this species 1n the hunting territory or these

foxes

~ne horned puffin and tufted puffins are less vulnershy

able to predation than the auklets due to their comparashy

tively inaccessible nest sites and also to their diffe~ent

behavioral characteristics In-~neral these species

-oeclpy ure lH-et~i~itcus cliffs and seem more alert to intrushy

ders The number of puffins represented in the food reshy

mains reflects their lesser vulnerability The reason for

the greater number or horned puffins versus the number of

tufted puffins in the remains is not known

The cliff-nestin~ birds most 1naccess~ble to the foxes

are undoubtedly the murres 1 cormo~ants and larids

Despite the foxs tretlendous a~ility it would be difficult

indeed for them to capture these birds on the sheer escar~shy

ments where these species typically nest Though some

adults and young are eaten by the foxes many of these

probably die fromother causes such as rock-falls or are

fallen nestlings that have been picked up on the rocks

below

middotmiddotmiddotmiddotmiddot--

The comparison or data from the dens east of Boxer Bay

with that from dens west of this bay revealed that the

q character or the uplands adjacent to cliffs has a signifi-Iii cant influence on the diet or foxes inhabitinv areas near

the alcid nesting colonies Th~ proximitY of wet and mesic

tundra east or the bay and the result~~t greater availabilitymiddotmiddot or small mammals was reflected by the significantly ~eater

occurrence or small mammal remains in scats colleated here

as compared to those collected to the west where tle inland

I bull areas are predominantly rocky barrens The nature or the

cliffs themselves also influences the occurrence or ~ood

items in the diet The s1pn1ficantly lower occurrence or

egg shells in scats collected east of Boxer Bay is p1bullobably

due to the sxraller number of auklet nests on the area and

to the more inaccessible nature of the seabird nests that

are present

l In spite of the almost total dependence on alcid popu-

III lations for summer food by foxes denning near the nestin~ I

colonie 1 predation is probably -nnwhe1bulle s~fcant in

terms of the proportion of the alcid population affected

The number of birds taken probably varies with the relative

population levels of alcids and foxes Hi~her alcid popushy

lations ~rould probably cause a greater number middotor relatively

accessible nest sites to be used

Shibanorr (1951 noted that the greater the abundance

of food the mere restricted 1s the daily ran~e o~ the arcshy

tic rox Thus 1 it is significant that the tremendous

avian biomass found on the cliffs was used only lizhtly by

foxes denning in the neaLmiddotJ~ Bcler iver valley The data

indicate 1 rather that the foxes in this valley relied

almost entirely on small mammals 1 especially ~he tundra

vole as their summer ood resource Tho1J~rh the prey comshy

munity of the tundra was not as spectacular in terms of

apparent activity as the prey community of the sea cliffs

it was of sufficient availability tc sunport a summer rox

population compable in density to that ound alonrlt the

cliffs

~ne remains of various species c fish and narine

invertebrates have been noted in the diet or island roxes

and in some instances are used extensively (Lavrov 1932

Barabash-Ukiforov 1 1941 Braestru~ 1 19~1 Tones (viva

voce) reports that marine invertebrates particularly

amphipods ~~e an essential component ot the diet on some

of the Aleutian Islands The above items occur only rarely

however in the summer diet on St Lawrence Island Insects

occurred at a similmiddotarly low frequency Vegpoundtation 1 soil

and fox hair 11ere considered to be items ingested incidental

to feeding activities and occurred only in trace amo~~ts

Similar occurrences have been noted by numerous other

workers

Beach carrion appears to be a minor item in the su~~er

diet Carcasses or marine mammals were pr-esent on the beach

69

during the summer but remains of these food resources were

found in only a few scats Further little fox activity or

sign was observed middotalong the beach and there was no evishy

deace of foxes feeding on carcasses o~ seal sea lion or

~alrus Apparently the summer availability or small mamshy

IrAls and birds is such that foxes are not required to utishy

lize carrion at this time Trap~ers on the island report

that the me~t of marine mammals th~t is set out as bait in

the fall attracts foxes durinll and after november but not

before and Schiller (1954) round abundant evidence of

foxes feeding on a number of dead walruses a~ong the northshy

east coast of the island in winter Thus 1 carrion is proshy

bably an important food reource only in mid-to-late ~ofinter

The data indicate that 1 in ~eneral the summer diet ofmiddot

arcti~ foxes on St Lawrence Island clearly reflects re~ional

differences in the composition of the prey population

Foxes living alon~ the cliffs feed mainly on alcids while

tundra foxes feed mainly on voles The arctic fox has often

been described as an opportunistic11 predator and scavenger

Obulltineyev 1946 Braestrup 1941 Chesemore 1967) and this

term may well a~ply to the winter food habits of the foxes

on St Lawrenc~ land Though the summer ~iet does indishy

cate a strong response to availability the foxes are no~

entirely opportunistic in their food habits durin~ this

season or rood abundance The results of my study indicate

that durin~ the summer of 1968 1 the foxes relied almost

70

entirely on recently ca~tured prey despite a ~lentiful

supply of marine mammal carrion Further the atnmila-tshy

passerines and shorebirds were little utilized and the

tundra shrew was nearly absent from the diet indicatin~

that the fox expends little huntin~ effort on these items

~rhen other larger ~rey are available The fact that the

foxes can afford the luxury of predilection su~rests that

the summer food sup~ly on the island is more than adequate

~or the population or foxes
