One of two Caspian Terns photographed flying over the Presumpscot River from the North Meadow at Gilsland Farm. Approximately 2300 feet away, as measured on Google Earth.
观察细节
*uncommon | patch bird #208 | large tern first spotted by Derek Lovitch flying up river and eventually making several passes between a large gap in the trees; on one of the final passes we realized there was actually a second CATE as they were viewed flying together. Large, heavy bodied tern with thick neck. White on the body with a black gradient in the primaries. Black cap looked complete (presumably an adult). Thick red-orange bill only visible (to me) through the scope.
