We analysed the relationship between the timing of hatching and the timing of autumn migration in first and second brood Great Tit Parus major young. Second brood birds were recognised in autumn by the incomplete moult of their tail feathers. In[...]

Constant effort mist netting sites are widely used along the Palearctic-African migration system in areas north of the Sahara to collect standardised migration data. However, in sub-Saharan Africa such sites are scarce. We present data collected[...]

According to calculations, the annual proportion of non-breeding males in the Pied Flycatcher Ficedula hypoleuca in a study area in Lower Saxony (LS), Germany, was about 80% in yearlings (Sternberg, 1989). In order to detect non-breeders in popu[...]

After breeding, Asian and European Black Terns Chlidonias niger concentrate in two European wetlands, IJsselmeer (The Netherlands) and Sivash (Ukraine), prior to their non-stop migration to wintering areas in coastal West Africa. Studies on thei[...]

Primary moult and long-distance migration entail high energetic costs, which birds usually minimise by keeping the two processes separated. Post-breeding migration and primary moult largely overlap in the Black Tern Chlidonias niger, and two mou[...]

Most Common Terns return at the age of two years to their natal colony site and recruit after one or more years prospecting. Whereas this general pattern is known, the mechanisms regulating recruitment are poorly understood. This paper reports o[...]

Pied Avocets Recurvirostra avosetta breeding in the same colonies on the German Wadden Sea are known to winter in France, the United Kingdom and The Netherlands ('the North') or about 1000 km further south west in Portugal, SW Spain and Morocco [...]

Long-distance migrants have to pass enormous barriers during their seasonal movements, and this is especially true for the birds that breed in Central Palaearctic and spend the winter in Africa. These birds have to cross the highlands and desert[...]

Analyses of long-term data indicate that human-caused climatic changes are affecting bird phenology in directions consistent with theoretical predictions. Here, we report on recent trends in the timing of spring arrival and egg laying found with[...]

Coalescent analysis is a useful tool for relating the historical relationships among gene lineages to the demographic parameters of populations. In this paper I show how simulations of the coalescent process can be used in three species of migra[...]

This review attempts to describe how birds perceive photoperiod and how this controls their physiology so that breeding and moult occur at the appropriate times of year, and to contrast this with the situation in mammals. The breeding seasons of[...]

The apparent nomadism of Palearctic migrant birds during the wintering period in Afrotropical savannah resulted in their characterisation as wandering interlopers, subordinate to Tropical residents, forced to subsist on temporary resource concen[...]

The pattern of the present migration routes and winter distribution of a species is the consequence of historical factors (re-colonisation from Ice-Age refugia), and of more recent evolutionary mechanisms superimposed upon this base. The present[...]

A strong decline of Shorelarks Eremophila alpestris, Twite Carduelis flavirostris and Snow Buntings Plectrophenax nivalis has been noted in the breeding and wintering areas. In the wintering areas in the German Wadden these species roost mainly [...]

Some migratory birds refuel at stopover sites that they by-pass on the return trip. In theory, this skipping behaviour is only expected in time-selected migrants when the overflown site is of a lower quality than the departure site. We provide e[...]
