Canvasback
A road trip with two friends to some birdng along the Detroit River yesterday.
We ha hoped there would be more ice which would bring the ducks, geese, swans, and eagles in closer, but you take what you get.
Aythya valisineria.
The species name of the Canvasback, valisineria, comes from Vallisneria americana, or wild celery, whose winter buds and stems are the duck’s preferred food during the nonbreeding period.
The oldest recorded Canvasback was a male, and at least 22 years, 7 months old when he was shot in California in 1991. He had been banded in the same state in 1969
