觀察細節

Good views of these birds perched with a Forster's and a Caspian on posts near shore in Lake Pontchartrain at the end of the road. Bald-headed look. A nice chance to see their orange bills which looked similar to the more familiar Elegant but definitely a little thicker and blunter. Also got brief views of some of them in flight as they shifted around. Looked lankier and proportionally longer- or thinner-winged than Caspian.
