DOI: 10.1016/j.yhbeh.2022.105139
Abstract: Twice a year, billions of birds take on drastic physiological and behavioural changes to migrate between breeding and wintering areas. On migration, most passerine birds regularly stop over along the way to rest and refuel.… read more here.

DOI: 10.1038/s41598-021-81274-9
Abstract: What determines why some birds migrate and others do not? This question is fundamental to understanding how migratory systems are responding to environmental changes, but the causes of individual migratory behaviours have proven difficult to… read more here.

Telomere length predicts timing and intensity of migratory behaviour in a nomadic songbird

DOI: 10.1098/rsbl.2022.0176
Abstract: Our understanding of state-dependent behaviour is reliant on identifying physiological indicators of condition. Telomeres are of growing interest for understanding behaviour as they capture differences in biological state and residual lifespan. To understand the significance… read more here.

DOI: 10.1111/mec.16724
Abstract: Recent ecotypic differentiation provides unique opportunities to investigate the genomic basis and architecture of local adaptation, while offering insights into how species form and persist. Sockeye salmon (Oncorhynchus nerka) exhibit migratory and resident (“kokanee”) ecotypes,… read more here.

Age-related changes in migratory behaviour within the first annual cycle of a passerine bird

DOI: 10.1371/journal.pone.0273686
Abstract: First time migrants (juveniles hereafter) of many species migrate without specific knowledge of non-breeding locations, but experience may aid adults in timing and route decisions because they can migrate more efficiently to their previous non-breeding… read more here.

Flyways and migratory behaviour of the Vega gull (Larus vegae), a little-known Arctic endemic

DOI: 10.1371/journal.pone.0281827
Abstract: Large gulls are generalist predators that play an important role in Arctic food webs. Describing the migratory patterns and phenology of these predators is essential to understanding how Arctic ecosystems function. However, from all six… read more here.
