New article published in Ornis Fennica! García Miranda et al. 2025: Migratory protogyny and condition-dependent arrival in Icelandic Red-necked Phalaropes. https://ornisfennica.journal.fi/article/view/143438.

In many migratory birds, arrival at breeding grounds is s*xually asynchronous. This pattern is often explained by the idea that early arrival benefits the s*x under stronger s*xual selection by improving access to mates through territoriality. However, in species where females arrive first and are n...

New article published in Ornis Fennica! Hamedani Raja et al. 2025: Crested T**s prefer pine forest but not mature forest: insights from an early spring passive acoustic survey.

The Crested Tit (Lophophanes cristatus) is a relatively common species in Finland but is declining likely due to increasing anthropogenic pressures and habitat degradation. Here, we study habitat preferences of Crested T**s in Southwest Finland. We conducted a passive acoustic survey of the species....

New article published in Ornis Fennica! Matejka et al. 2025: Winter site fidelity of the Great Tit (Parus major) revealed by recaptures of individuals roosting in nest-boxes.

Birds often return to the same locations where they have previously bred successfully or survived the winter, demonstrating site fidelity. This behaviour extends beyond breeding sites to include roosting and feeding areas, with individuals frequently recaptured at the same locations across years. In...

New article published in Ornis Fennica! Meissner & Kozakiewicz 2025: Local variation in s*x ratios in three species of wintering ducks: the need for large-scale sampling. https://ornisfennica.journal.fi/article/view/160744

This study investigates the hypothesis that site characteristics and flock size influence the s*x ratios of wintering ducks by examining three species: the Mallard (Anas platyrhynchos), the Goldeneye (Bucephala clangula), and the Long-tailed Duck (Clangula hyemalis) in the Gulf of Gdańsk, southern ...
