Podrobnosti k pozorování
After seeing Rob Hewitt’s eBird post yesterday, Chris Allen and I decided to check out the swan at Mono Lake this morning. We arrived about 10am and found a swan at the end of the county park boardwalk. As it was a lone swan we ended up spending a lot of time studying it, but felt it was a Trumpeter Swan. The bill on this bird seemed very long and appeared entirely black. The top of the bill was a bit knobby, not slightly concave as in Tundra. There was a nice straight line from the inside “corner" of its bill to its eye, and the eye was well-surrounded by black, not just barely connected to the rest of the bill color by a skinny little pedicel. The most difficult feature for me to see on this bird was the V-shaped border to the forehead. To both Chris and I the border looked sort of “in between” Tundra and Trumpeter. Only at certain angles in the field could I really see the V-shape because of dirt on its head. When I downloaded my photos and zoomed into the forehead, I could see that there was dried up mud caked onto the birds forehead, obscuring the shape in the field for us.
