Dry conditions have meant fewer birds in spots that I normally visit, but last Sunday there was activity at the San Bernard refuge. A small flotilla of what appeared to be Blue-winged Teal (Spatula discors) was accompanied by a pair of American Coots (Fulica americana) and — to my amazement — a single Scaup: the bird with the solid brown head on the right.
The Lesser Scaup (Aythya affinis) and Greater Scaup (Aythya marila) are easily confused. One field mark is the shape of the head; after much pondering, I decided this one’s head is more round than peakèd, indicating a Greater Scaup. Clicking to enlarge the photo will provide a closer view of these beautiful birds.
The Coots, easily recognizable by their black bodies and white bills, are a common winter bird that sometimes appear at the refuges in great numbers. With a strong front predicted for this coming weekend, I expect to see many more. Other species — Gadwall, Bufflehead, and Pintail — are arriving now, and the unmistakable sound of Sandhill Cranes filled the air as I watched these ducks. The season is turning, indeed.
