Recent developments in GPS tracking technology allow the movements of bird species to be followed in ever-greater detail. Seabird research is benefiting greatly, due to the challenges of tracking species that often roam widely out at sea. Amongs[...]

Arctic Terns Sterna paradisaea have a record long migration between their breeding grounds in the Arctic and wintering areas in the Antarctic. Nevertheless, return dates to north Norway were remarkably constant over a 35-year period (1981–2015),[...]

In the majority of the Phylloscopus warblers there is no sexual plumage dimorphism and this makes it almost impossible to determine the sex of birds trapped during migration. We analysed a data set of 6287 individuals of seven warbler species ri[...]

Gulls are monomorphic in plumage characteristics but show a sexual size dimorphism where males are larger than females. In this study, we use discriminant function analyses (DFA) and generalised linear modelling (GLM) to provide sexing criteria [...]
