The relation between wind, latitude and daily migration speed along the entire migration route of white storks was analysed. Mean daily migration speed was calculated using satellite telemetry data for autumn and spring migration of white storks[...]

We use data on pigeon guillemots Cepphus columba to test the hypothesis that discretionary time in breeding seabirds is correlated with Variance in prey abundance. We measured the amount of time that guillemots spent at the colony before deliver[...]

Although trogons (Aves, Trogonidae) are well characterized by the possession of heterodactyl feet, their phylogenetic relationships to other extant birds still are only poorly understood. Molecular studies did not show conclusive results and the[...]

In tree swallows Tachycineta bicolor, last-laid eggs typically hatch one to two days after the other eggs in the clutch hatch, putting last-hatched offspring at a disadvantage when competing for food delivered by parents. We studied the biology [...]

We examine the provisioning constraints of a pursuit-diving seabird in a cold ocean regime by comparing the behaviour of common murres Uria aalge rearing chicks at two colonies in the Northwest Atlantic during 1998-2000. Funk Island is the large[...]

On the offshore island Helgoland, passerine birds killed by predators (feral cats Felis catus and raptors, mainly sparrowhawks Accipiter nisus) during Stopover were measured and weighed when found freshly killed and still intact. Supplemented by[...]

High densities of penguins in their colonies and the continuous use of these sites over consecutive reproductive periods increase the risk of development of tick populations. We have studied the effects of tick parasitism by Ixodes uriae in a co[...]

This paper summarizes and discusses the many new insights into passerine evolution gained from an increased general interest in avian evolution among biologists, and particularly from the extensive use of DNA sequence data in phylogenetic recons[...]

Recently Carter et al. (2000) have shown that it is possible to amplify microsatellite markers from the DNA of spermatozoa trapped in the perivitelline layers of avian eggs. This makes it possible to establish whether sperm reaches the ovum and [...]

We tested the importance of nest cleaning in egg rejection behaviour of the great reed warbler Acrocephalus arundinaceus in a highly parasitised population in which about 64% of nests are parasitised by the common cuckoo Cuculus canorus. Three t[...]

There is considerable evidence that reproductive success improves with age in birds. It is often suggested that improved performance of older birds is because they are more experienced. Less consideration has been given to the possibility that i[...]

The effects Of simulated goose grazing oil common saltmarsh-grass Puccinellia maritima plants were tested on a Danish salt marsh during the flightless moulting period of greylag geese Anser anser (3-21 June 1998). Plants in all area exclosed fro[...]

It has long been suggested that competing groups of social animals assess one another on the basis of communal vocalisations, but so far this has only been demonstrated in mammals. We investigated this idea in the subdesert mesite, a roup-living[...]

Theoretical models of short-term avian behaviour Suggest that small birds adaptively balance the ecological costs and benefits of winter fat to maximize Survival probability. When low starvation risk eliminates benefit but not cost of fat, birds[...]

Using daily counts of birds seen at six coastal bird observatories in southern and eastern England, we explored the migration phenology of turtle doves during the period 1963 to 2000. Annual totals increased threefold up to the late 1970s then d[...]
