Article
Grzegorz Zaniewicz, Auteur ; Agnieszka Ożarowska, Auteur ; Nathan Sheeran, Auteur ; Marta Witkowska, Auteur ; Włodzimierz Meissner, AuteurForaging habitat preferences and migration route selection in avian migrants may correlate with the accumulation of energy stores and their expenditure, which in turn influence migrants’ ability to cover distances between staging sites and shape[...]

Article
Katarzyna Stepniewska, Auteur ; Agnieszka Ożarowska, Auteur ; Przemyslaw Busse, Auteur ; Pavel Zehtindjiev, Auteur ; Mihaela Ilieva, Auteur ; Oksana Hnatyna, Auteur ; Wlodzimierz Meissner, AuteurIn this study, we investigated fattening strategies of juvenile Sedge and Reed Warblers during their autumn migration. We analysed fat scores of birds captured at five ringing sites situated between the southern Baltic Sea coast and Asia Minor. [...]
Article
Grzegorz Zaniewicz, Auteur ; Wlodzimierz Meissner, Auteur ; Agnieszka Ożarowska, AuteurFat is the main source of energy during bird migration, and the visual fat scoring is widely used in the studies on, e.g., stopover ecology of migratory species. Yet, visual fat scoring can lead to wrong conclusion due to potentially different p[...]

Piotr Minias, Auteur ; Włodzimierz Meissner, Auteur ; Radosław Włodarczyk, Auteur ; Agnieszka Ożarowska, Auteur ; Anna Piasecka, Auteur ; Krzysztof Kaczmarek, Auteur ; Tomasz Janiszewski, AuteurMigration is an energetically expensive and hazardous stage of the annual cycle of non-resident avian species, and requires certain morphological adaptations. Wing shape is one of the morphological traits that is expected to be evolutionarily sh[...]

Jan A. van Gils, Auteur ; Simeon Lisovski, Auteur ; Tamar Lok, Auteur ; Włodzimierz Meissner, Auteur ; Agnieszka Ożarowska, Auteur ; Jimmy de Fouw, Auteur ; Eldar Rakhimberdiev, Auteur ; Mikhail Y. Soloviev, Auteur ; Theunis Piersma, Auteur ; Marcel Klaassen, AuteurReductions in body size are increasingly being identified as a response to climate warming. Here we present evidence for a case of such body shrinkage, potentially due to malnutrition in early life. We show that an avian long-distance migrant (r[...]

Article
Agnieszka Ożarowska, Auteur ; Katarzyna Stepniewska, Auteur ; Wed Abdel Latif Ibrahim, AuteurFour ringing stations of the SE European Bird Migration Network in Egypt (at the coasts of the Mediterranean and Red seas, in the Nile Valley, and at the northern edge of the Sahara) provided data on birds resting in adequate habitats. At three [...]
Article
Katarzyna Kopiec, Auteur ; Agnieszka Ożarowska, AuteurA migration route leading central European breeder Blackcaps to their winter quarters in Britain and Ireland was discovered in the 1960s. This phenomenon, representing a rapid evolutionary change of migratory behavior, can be explained by a shif[...]
Article
Agnieszka Ożarowska, Auteur ; Grzegorz Zaniewicz, AuteurSeveral avian species respond in the timing of their annual cycle events to recent climate change and large-scale climate phenomena. We studied autumn migration timing of Blackcaps differentiated by their wing length, i.e., short-, medium- and l[...]
