Mutual benefits of associations between breeding and non‐breeding White‐fronted Geese Anser albifrons
The relationships between yearlings and adult pairs of White‐fronted Geese Anser albifrons were studied during pre‐nesting, laying and early incubation in the central Canadian Arctic. Prior to nesting, females of lone pairs spent 75–81% of their time feeding, while males spent only 42–47% of time fe...
