Reproduction of the white‐tailed sea eagle Haliaeetus albicilla in Sweden
Ecography, 1985 Sixty‐eight white‐tailed sea eagle territories were studied on the Swedish Baltic coast in 1964–1982 and 22 territories in Swedish Lapland in 1976–1982. Older data were assembled for comparison. The breeding frequency of adult pairs was high in both study areas (ca. 90%). Median egg‐laying dates were 17 March (Baltic) and 7 April (Lapland).

International Journal of Osteoarchaeology, Volume 36, Issue 3, Page 537-553, May/June 2026.ABSTRACT Studying goose domestication through archaeological finds has been challenging due to the similar skeletal morphology of the European domestic goose and its wild progenitor, the greylag goose (Anser anser). We analyzed stable carbon (δ13C) and nitrogen (δ15N) isotopes from bone collagen of subfossil domestic and potentially domestic geese to ...

Apparent Survival of Territorial Golden Eagles Using Non‐Invasive Genetic Profiling
Ecology and Evolution, Volume 16, Issue 1, January 2026.In a novel study for the species, DNA was extracted from moulted feathers over 4 years involving 21% of the Scottish population of territorial golden eagles, and individuals' genetic profiles were analysed for apparent survival rates. Results showed sexual differences but not between two sub‐populations; very few cases of breeding dispersal were ...
