In many colonial bird species there is considerable intraspecific variation in colony size and inter-nest distance (colony density). Possible causes of this variation and its effects on hatching success (survival of eggs) and breeding success (p[...]

We present a new type of equation to describe the growth patterns of procellariiform seabirds and other species a-hose chicks characteristically lose mass towards the end of the rearing period. Our equation is based on the Gompertz curve; our pr[...]

Unlike most seabird families, the vast majority of small petrel species are nocturnal on their breeding grounds. Further, they reduce markedly their activity when the light level increases. Moonlight avoidance might he a consequence of reduction[...]

Throughout the range of the Scarlet Rosefinch, its territorial song consists of 3-9 (usually 4-5) elements, of which there are 5 different types. The differences lie in the way the pitch of the element changes in time (frequency "slope") and the[...]

Seabirds' behavioural activity budgets have been proposed as an indicator of changes in marine food supplies. Reduced recruitment and a low biomass of sandeels Ammodytes spp. around Shetland in the late 1980s were associated with a dramatic incr[...]

Current theory and empirical evidence suggests that, if a character is sexually dimorphic as a result of sexual selection, it should be positively allometric (i.e. relatively larger in larger individuals), whereas if the dimorphism is the result[...]

A recent hypothesis suggested that bird song repertoire size is a reliable indication of male quality because the number of songs emitted by an individual and the expression of many traits important for fitness are highly dependent on developmen[...]

In response to unpredictability of both food availability and core offspring failure, parents of many avian species initially produce more offspring than they commonly rear (overproduction). When parental investment is insufficient to raise the [...]

Experimental Hoopoe Upupa epops songs prepared with synthetic sound to differ in strophe length were used to test whether Hoopoe females prefer long strophes. The songs were broadcast simultaneously in the field from two loudspeakers situated 10[...]

We studied the reproductive biology of a box-nesting population of Tree Swallows Tachycineta bicolor in southeastern Wisconsin, USA. We were interested particularly in the relationship between laying order and hatching order and the extent to wh[...]

Population structure and gene how were inferred from isozyme variation at 26 loci among five populations of Limnothlypis swainsonii (Swainson's Warbler; Parulidae), a Nearctic-Neotropic migrant songbird breeding in the unglaciated southeastern U[...]

The foraging range and principal feeding areas of White-chinned Petrels breeding at South Georgia were determined using satellite telemetry. Foraging trips during incubation lasted 12-15 days and covered 3000-8000 km and 2-11 days and 1100-5900 [...]

Recent studies have suggested that the size of avian clutches may be determined in part by the costs of egg production, which are thought to involve the depletion of endogenous nutrient reserves. I tested the hypothesis that producing extra eggs[...]

The chick provisioning behaviour of Short-tailed Shearwaters Puffinus tenuirostris breeding at the northern edge of their distribution on Montague Island, New South Wales, was examined in February and March 1997. The duration of individual forag[...]

We studied several determinants of laying date variation and the relationship between laying date and reproductive success in the Snow Petrel Pagodroma nivea. The effects of female body size and condition, year, individual laying period, colony [...]

We develop a new approach to quantifying habitat use within the foraging ranges of satellite-tracked seabirds. We applied kernel estimation techniques to 167 days (3738 locations) of data from Black-browed and Grey-headed albatrosses Diomedea me[...]

In this study, we tested whether conspecific brood parasitism (CBP) has selected for egg rejection behavior in the colonial Great-tailed Grackle Quiscalus mexicanus. No evidence of CBP was recorded at 797 Great-tailed Grackle nests, and we did n[...]

Calcium availability might Limit reproductive output in birds either by effects on eggshell formation or on skeletal growth of nestlings. Quantitative data on calcium intake by nestlings of free-living passerines are needed to test the second hy[...]

The presence of density dependence of clutch size is tested in 57 long-term population studies of 10 passerine bird species. In about half of the studies of tit species Parus spp. density dependence of clutch size was found, while none was found[...]
