Yesterday on Quintana Island in Texas I had this coot with pink bill - shocking contrast compare to a ‘normal’ looking coot around here (had seen millions of American Coots before - none had pink bill, all had white ones).
So you tell me - it is a aberrant form or? Closest photos I found are showing Hawaiian Coots ('Alae ke'oke'o )
P.S. More photos and notes on behavior later this evening - if it is something interesting.
