观察细节
Photo. This is an example of a "white-shielded" male, among the North American populations of American Coot, that we used to help debunk claims of "Caribbean Coot" in Florida in our paper -- Roberson & Baptista (1988) "White-shielded coots in North America: a critical evaluation," Am. Birds 42: 1241-1246. I believe eBird wants us to enter such birds in this category.
