On top of their annual migration to warmer climes and back again, Canada Geese may also take on a moult migration. What is the purpose of this trip? A. Flying allows the geese to lose their flight feathers more easily than preening alone. B. They seek out their breeding grounds. C. Since they can’t fly while they wait for their flight feathers to grow back, they need to get to a spot with a lot of open water, where they can escape predators.
Correct Answer: CCanada Geese head north between late May and early June to scout out areas of open water and protein-rich food, where they can hunker down for the four- to five-week moulting period. Since they lose their flight feathers all at once, they need to live in areas where they can escape predators while they wait for their new feathers to grow in.
