観察結果の詳細
First saw one adult perching on snag in vicinity of Limpkin. Flew when man with fishing net approached along shoreline. Later seen with another mature adult and a juvenile—all three perching together near spillway. Adult birds with black crown and back, white below eye, gray wings and pale gray underparts, red eyes. Hunched appearance with neck tucked. Juvenile bird with similarly hunched appearance with neck tucked; yellow eyes; brown body with white streaks, and diagnostic white teardrops on wing coverts. Bill shape similar on adults and juvenile—thick with pointed tip. Family group suggests reproduction in the area. Photo to follow.
