Least Terns Mating, Cape May, New Jersey
A few years back, I was down on the Delaware Bay photographing the curious, yet not entirely surprising mating ritual of the least tern. Male least terns catch a fish and then use that fish as payment for services rendered by the female. I watched while lying face down on the sand and took many low perspective photos of this pair as he returned from the sea and showed her the fish. Satisfied with what she saw, she allowed him to mount her and do his thing — about a 3 minute performance. The whole time, he kept the fish in his mouth, shaking his head back and forth until finished. Then she turned around and he dropped the fish, not in her mouth, but rather unchivalrously to the side, as if not completely satisfied. Both, however, seemed to get what they wanted and flew off in opposite directions. I had been watching several other terns doing the same thing and noticed that sometimes the female was not satisfied with the fish and refused the male, while other times the male checked out the female, fish in his mouth, and decided that she wasn’t worthy and flew off in search of another female. These two were the only ones that allowed me a close enough approach to capture the action.
