John James Audubon,
Ornithological Biography
(1831)
“ When the Fish Hawk has attained its utmost elevation, which is sometimes such that the eye can no longer perceive him, he utters a loud shriek, and dives smoothly on half-extended wings towards his nest. But before he reaches it, he is seen to expand his wings and tail, and in this manner he glides towards his beloved female, in a beautifully curved line. The female partially raises herself from her eggs, emits a low cry, resumes her former posture, and her delighted partner flies off to the sea, to seek a favourite fish for her whom he loves. ”
