A large number of horned grebes are currently at Erieau, Ontario.
I saw at least 11 at one time in various plumages.
This one had just caught a small fish.
Familiar to most North American birders in its black-and-white winter plumage, the Horned Grebe is more striking in its red-and-black breeding feathers. Its "horns" are yellowish patches of feathers behind its eyes that it can raise and lower at will.
