Journal ArticleDOI
Movement patterns of adult male ovenbirds during the post-fledging period in fragmented and forested boreal landscapes
Erin M. Bayne,Keith A. Hobson +1 more
TL;DR: In this article, radio-telemetry data was collected from 44 male Ovenbirds (Seiurus aurocapillus) during the post-fledging period to determine if movement patterns differed in landscapes dominated by agriculture versus those dominated by forest.
Journal ArticleDOI
Comparison of trace element and stable isotope approaches to the study of migratory connectivity: an example using two hirundine species breeding in Europe and wintering in Africa
Tibor Szép,Keith A. Hobson,Judit Vallner,Steven Piper,Béla Kovács,D. Z. Szabó,Anders Pape Møller +6 more
TL;DR: The results of both methods suggest that food composition and/ or source differs between adults and nestlings in the breeding area and that food and/or molting location changes with the age of individuals in Africa.
Journal ArticleDOI
Summer diet of king penguins (Aptenodytes patagonicus) at the Falkland Islands, southern Atlantic Ocean
TL;DR: It is emphasized that king penguins are specialist myctophid eaters throughout their breeding range in summer, and the importance of Protomyctophum choriodon as a link between zooplankton and top predators in the pelagic ecosystem of the southwestern Atlantic Ocean is highlighted.
Book ChapterDOI
Isotopic tracking of migrant wildlife
TL;DR: Rubenstein & Hobson (2004) provided a review of the relative advantages of using intrinsic vs. extrinsic markers to track animal movements, and the use of stable isotopes in animal tissues.
Journal ArticleDOI
On the use of stable oxygen isotope (δ (18)O) measurements for tracking avian movements in North America.
Keith A. Hobson,Geoff Koehler +1 more
TL;DR: A much broader sampling of both isotopes in the same keratinous tissues across precipitation isotope gradients and across taxa is advocated to resolve this issue and to increase the power of using water isotopes to track migratory animals.
