Timing and duration of spring staging of the Eurasian Greater White-fronted Goose (Anser albifrons albifrons) in relation to sex, age and progress of migration season
Among Arctic-breeding waterfowl species, spring stopovers 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...
