Frank Finn, The Zoologist (1902)
“ On another occasion the carrying parent, on my approach, swam away from the nest with the young on its back, and the other hastened to it, and there was much chattering. Then the unburdened parent swam to the nest, made a peck at it—I being there all the time on the platform overlooking it—and then went back to its partner, when there was more chattering. The whole performance looked as if this bird had inquired as to the cause of its partner's alarm, and had gone to reassure it by examining either me or the state of the nest! I have no doubt that the old birds know me. ”
