Under her wing
This Canada Goose had a day-old(?) fluffball that had already hatched, and she was still incubating the rest of her clutch. The baby retreated under its mother's wing as danger (us!) approached.
Normally we would take great pains to avoid disturbing nesting birds -- but we're not too worried about Canada Geese. Several pairs have nested right alongside the trail along the lakeshore here.
