She is a 5 year female and this is her first nesting season. You will see some dark feathers in her head and tail still. She gets up at 1:18 to shake the snow off her and she does a ps over the side at 2:25 - notice it is black. The excrement is part of the metabolic process - but I have never seen it dark like this before. She has been on the eggs all day and night.

Birds are exquisitely adapted to survive in bad weather. It starts with the feet. Although that cold, wet ground is uncomfortable for you, it isn’t particularly uncomfortable for a bird. Those spindly little legs have a wonderful adaptation called counter-current exchange. We mostly lose heat, and thus feel cold, from hot blood in the skin radiating heat to the cold air. The loss of heat brings cold blood back to our body’s core, which chills us even more.
In birds, the arteries with hot blood running to the feet pass right next to the cold blood running in the veins back to the body. With this arrangement, the hot blood in the arteries passes heat to the cold blood in the veins before the blood even reaches the feet. The heat is thus returned to the body and results in colder blood in the feet. Cold feet lose very little heat to the cold ground. The colder blood is sufficient to keep the feet from freezing.

A second adaptation is feathers. There is a reason why we covet down jackets for their warmth. The feathers are exquisitely able to trap air. This trapped air prevents cold air from circulating to the skin, thereby creating very effective insulation—and the fluffier the feathers, the better the insulation. Birds can adjust the amount of “fluff” in their feathers. Small birds living in the Arctic can fluff their feathers sufficiently to survive temperatures many dozens of degrees below zero Fahrenheit.

Thank you for watching!
