Timing and duration of spring staging of the EurasianGreater White-fronted Goose (Anseralbifronsalbifrons)in relation to sex, age and progress of migration season
Amon gArctic-breedin gwaterfowl species, sprin gstopovers are critical to individuals as a means to accumulate fat and nutrient stores to invest in both migration and their breeding attempt in the tundra zone. We studied the influence of possible factors (age, sex, progress of migration season) on t...
