for that matter. Data concerning these

two recoveries are as follows:

recovery date).

Only 32 recoveries have been made

since extensive ringing was started at

Flatey in lg7 3, and only 5 of these were

from outside the breeding season, in-

cluding the rwo from Greenland. on the

basis of these recoveries, it is hypothesized

that Icelandic Black Guillemots may

d esert the vicinity of Iceland during

winter in aPPreciable numbers, at least

at certain ug.t. If that is true and a

lot more material is needed to draw arry

firm conclusions it would be in direct

contrast with f ormer ideas about the

movemenrs of the Icelandic Black Guille-

mot population (..g. Timmermann 1949'

Gudmundsson 1953).
