Mapping of ringing recoveries gives very impressive migration patterns that are, however, often misleading. Most of people looking at them believe that almost all European Passerines migrate SW to, or through, south-western Europe. But this impr[...]

A device for spraying dyes onto nearby birds for individually marking without obviously disturbance is described. It can be used in colonies and was successful tested in Common Terns. Up to eight sprayers can be triggered separately by remote co[...]

Nocturnal passerine migrants ringed at daytime stopovers can be retrapped at the moment of initiating nocturnal flight by the original method of high mist-nets. This technique was developed and applied at the field site 'Rybachy' where thousands[...]

The feasibility of using ring recovery data to distinguish obligate and facultative partial migration is examined. Possible approaches involve (1) the observation of temporal change in the proportion of migrant individuals, and (2) the identific[...]

Vladimir A. Fedorov, Auteur
Breeding and natal dispersal of the Great Reed Warbler (Acrocephalus arundinaceus) were studied in the southern part of the Pskov Region and on the Courish Spit on the coast of the Baltic Sea. As with many other species, adults are more likely t[...]

During migratory stopovers on the small offshore island Helgoland (North Sea), Northern Wheatears equally used grassland and beach habitats in spring. An increasing proportion of wheatears present in beach habitats during autumn migration can be[...]

The world population of the African Penguin (Spheniscus demersus), a vulnerable species confined to South Africa and Namibia, is estimated to be 180 000 birds; 10 000 were oiled in the "Apollo Sea" spill in June 1994. Of the 5000 penguins that s[...]

Philopatry, especially natal philopatry, can vary noticeably even in related species. Ringing of nestlings and native juveniles on the Courish Spit revealed that in some species (Barred Warbler Sylvia nisoria, Willow Warbler Phylloscopus trochil[...]
