Changes in body mass and hormone levels between wintering and spring staging areas in dark-bellied brent geese Branta bernicla bernicla
We document seasonal changes in body mass and plasma hormone levels (testosterone and triiodothyronine) between winter and spring quarters in dark-bellied brent geese Branta bernicla bernicla. Body mass increased between winter and spring, whereas body size was the same for the birds sampled in wint...
