BRIDLED TERN
76. Sterna anætheta. 15 in.
Similar to the last, but the back and wings much lighter, and the white of the forehead extends over the eyes; nape whitish.
Range.—Breeds north to the Bahamas.
BLACK TERN
77. Hydrochelidon nigra surinamensis. 10 in.
Adults in summer with the head, neck and underparts, black; back, wings and tail, dark gray; eyes brown. In winter, the forehead, neck and underparts are white; nape and patch back of eye blackish.
In summer these little terns are found only in the interior, where they nest about marshy ponds. They are very pugnacious and will sometimes touch an intruder with their wings as they dart past. As usual with the family, they nest in colonies.
Notes.—A sharp “peek.” (Chapman).
