Body measurements and hormonal within-pair covariation in wintering and spring staging Dark-bellied Brent Geese Branta bernicla bernicla
International audience For long-term monogamous species, it may be important to have demographic, morphological, physiological and/or behavioural compatibility within pairs. We used field data on wild populations of Dark-bellied Brent Geese, a species showing extreme mate fidelity, to test for (1) w...
