[EBB Sightings] Flamingo @ Coyote Hills!

After bowing out from a GGAS trip this am to photograph before the harsh 
light got harser, at the first pond on Bay View trail after proceeding 
along past the gate and bearing left up the hill to the observation 
deck, I was surprised to see a Flamingo. I had assumed it was an 
escapee. The first bicylist that stoped attributed it to Katrina. Then I 
decided to check my Sibley and was surprised to find entries in the 
Western edition. It was not the Greater because it had no black on the 
undertail coverts; they were a brilliant salmon. It was not Chilean 
because the legs were uniform in color. My view was not good enough to 
see detail in the bill, but the back was a lovely shrimp color, not 
pale. I would hazard a guess at a Lesser Flamingo. (I have to wait for 
the film to come back). A third bicylist came up. When I told him about 
it,  he said that Flamingos were S. American  and he was surprised there 
weren't more. He then told me about the Chilean Flamingo which he sees 
when he goes home.
Has anyone else seen it? From the visitor center postings, a Flamingo 
has been seen for several weeks now.
