When do Canada Geese lose the abilty to fly?
Adults molt their primary flight feathers while raising their young. This renders the family flightless until after the eggs hatch. Thirteen different calls have been identified from that vary from loud greeting/alarm calls to soft sounds from feeding geese.
Groups are called: “gaggle”, “blizzard”, “chevron”, “knot”, “plump”, and “string” of geese.
