Migratory birds are able to use the sun and associated polarised light patterns, stellar cues and the geomagnetic field for orientation. No general agreement has been reached regarding the hierarchy of orientation cues. Recent data from naturally migrating North American Catharus thrushes suggests that they calibrate geomagnetic information daily from(More)
We used satellite tracking to study the migratory orientation of juvenile white storks from the population in the Kaliningrad Region (Russia) during their first autumn migration. Two series of experiments were performed. In the first series of experiments, several groups of first-year storks were raised in an aviary, kept there until all free-living(More)
In order to perform true bicoordinate navigation, migratory birds need to be able to determine geographic latitude and longitude. The determination of latitude is relatively easy from either stellar or magnetic cues [1-3], but the determination of longitude seems challenging [4, 5]. It has therefore been suggested that migrating birds are unable to perform(More)
Habitat use and habitat selection are essential for successful stopovers. Passerine migrants use habitats in a clearly non-random manner, even if many species utilise a broader range of habitats during passage than during breeding or wintering. Habitat selection proceeds as a sequence of events: landfall; search/settling, including redistribution across(More)

Vaccination with solubilized ZP or isolated ZP proteins can bring about infertility. Sometimes the effects are transient; alternatively, they can be long-lasting, but may be associated with(More)
Several studies have shown that experienced night-migratory songbirds can determine their position, but it has remained a mystery which cues and sensory mechanisms they use, in particular, those used to determine longitude (east-west position). One potential solution would be to use a magnetic map or signpost mechanism like the one documented in sea(More)
Migratory divides are thought to facilitate behavioral, ecological, and genetic divergence among populations with different migratory routes. However, it is currently contentious how much genetic divergence is needed to maintain distinct migratory behavior across migratory divides. Here we investigate patterns of neutral genetic differentiation among(More)
Spatial behavior and range of movements at daytime stopovers of three species of passerine nocturnal migrants (European robins, sedge warbler, and pied flycatchers) were studied by radio tracking. Both in spring and in fall, 94% of European robins remained within 350-400 m of their landing location (n = 51 and 65, respectively). Movements of robins became(More)
Dataset on departure fuel loads, stopover length and fuel deposition rate of the European robins Erithacus rubecula during their migration in the Baltic area is presented. We test these empirical data against the predictions of an optimal migration model assuming that robins minimize time spent on migration, and that fuel deposition rate varies(More)
It has been shown that songbird migrants can use several compass cues for orientation (e.g. sun position at sunset and possibly sunrise and related polarised light cues, stars and the geomagnetic field); therefore, the obtained information is redundant. This suggests that compasses of migratory birds must have certain hierarchical relationships and be(More)
