Stokes, A. W. (1960). Nest-site selection and courtship behaviour of the blue tit Parus caeruleus. Ibis, 102, 507-519.
Six pairs of blue tits were observed during 200 hours between mid-March and 7 May at Madingley Wood, Cambridge. Behaviour from the time of nest-hole selection by the male to incubation is described. It is concluded that bright plumage has evolved as enhancement of threat display, and its epigamic value is secondary.

Popham, E. J. & Lansbury, I. (1960). The uses and limitations of light traps in the study of the ecology of Corixidae (Hemiptera, Heteroptera). Entomologist, 93, 162-169.
Light-trap records have been used to provide evidence of migration in Corixids and to determine seasonal, diurnal and nocturnal flight periods, conditions favouring migration and sex differences in migrating Corixids. They cannot, without supplementary field observations, be used to deduce the composition of local populations, since species differ in their readiness to migrate, not all migrating species are equally represented at light-traps, some species require specialized habitats that may not be abundant near the trap, and some habitats tend to dry out and so induce migration. More detailed knowledge of the ecology of the commoner species might facilitate the interpretation of light-trap records.

Taylor, L. R. (1961). Aggregation, variance and mean. Nature, Lond. 189, 732-734. The distribution of individuals in natural populations varies between regularity (S2<m) and
contagiousness (s2>m), true randomness is only one of a continuous series of possible distribu- tions. Present methods of measuring aggregation are not entirely satisfactory. It is suggested that the relationship 52 = amb, in which the variance is proportional to a fractional power of the mean, and where a and b are characteristic of the population in question, is of value. The power b appears to be a true population statistic, an 'index of aggregation'.

on the fly is directly relatable to the arrangement of the setae. Desiccation appears the crucial factor in the mites' survival.
