Can you really change your stripes? Stable wing ornamentation suggests limited condition‐dependent signalling in female common eiders

open access: yesIbis, EarlyView.
Variation in the expression of white ornaments, such as flank spots or wing stripes, has previously been related to indices of individual quality in birds. We measured the white wing stripes of colour‐banded female common eiders Somateria mollissima in three islands in Iceland from 2014 to 2023, to determine whether the expression of these ornaments is

Connectivity between breeding sites, wintering areas, and migration routes in Common Terns (Sterna hirundo) breeding in the Western Palaearctic

open access: yesIbis, EarlyView.
Detailed knowledge about bird migration patterns can enhance our understanding of the evolution of migration and temporal changes in space use throughout the annual cycle. Additionally, as many migratory bird species are experiencing population declines, understanding the connectivity between their spatial distributions during breeding, migration and ...

Low breeding propensity in a declining Arctic‐breeding swan revealed by telemetry data

open access: yesIbis, EarlyView.
Many migratory bird populations are declining in the face of habitat degradation and climate change, making it important to identify which stages of their annual cycle are most affected in order to guide conservation measures. The Bewick's Swan Cygnus columbianus bewickii, an Arctic‐breeding waterfowl species, has suffered a dramatic population decline

Time‐stressed Bar‐tailed Godwits exploit novel prey during migratory fuelling

open access: yesIbis, EarlyView.
Long‐distance migratory birds breeding in the Arctic face challenges as earlier snowmelt shifts the timing of vital resources. To keep up with these advancements, birds will need to modify their migration. Higher fuelling rates during stopover have been identified as a critical mechanism for accelerating migration, but this requires adequate food ...

Geolocation reveals wintering sites of near‐extinct Caucasian breeding sea duck

open access: yesIbis, EarlyView.
We obtained 14 sets of full annual cycle geolocator tracks from 13 individual nesting female Velvet Scoter Melanitta fusca from the relict Caucasian population at their last remaining breeding site, Lake Tabatskuri, Georgia. Results showed that females wintered at widespread discrete localities in Ukraine, around the coasts of the Crimean Peninsula and

The demography of an Osprey population under natural recolonisation and translocation processes

open access: yesIbis, EarlyView.
In a context of global biodiversity loss, studying the processes underlying the recolonisation—whether natural or assisted—of expanding species provides essential insights for the development of effective conservation strategies. Since the 1980s, the Osprey Pandion haliaetus has naturally recolonized mainland central and eastern France, increasing from
