Horned Grebe (Podiceps auritus) - 06Dec2015 & 29Mar2016

Per the Cornell website:

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.

Here is a pic from Oak Island, NC in normal winter plumage:

And one from Wrightsville beach a little close to breeding plumage.  Unfortunately we don't really get them when they are in their full regalia as they are already up on the tundra.
