观察细节
Bird observed by our team for perhaps 90 seconds from very close range while on a stationary boat during waterbird colony monitoring. The bird appeared dark brownish gray above and mostly clean white below, appeared very long-winged and long-tailed, had white central underwings with complete fully dark margins, relatively bright pinkish feet (seen in one photo), and had effortless buoyant flight even while it was being mobbed by various waterbirds. The bird appeared healthy and strong, but was chased away from the waterbird colony and headed off towards open Lavaca Bay waters and was not seen again.
