Edmund Selous, Bird Watching (1901)
“ Always, however, or almost always, one of the birds—and this one I take to be the female—is more eager, has a more soliciting manner, and tender-begging look, than the other. It is she who, as a rule, commences and draws the male bird on. She looks fondly up at him, and raising her bill to his, as though beseeching a kiss, just touches with it, in raising, the feathers of his throat—an action light, but full of endearment. And in every way she shows herself the most desirous, and, in fact, so worries and pesters the poor male gull that often, to avoid her importunities, he flies away. ”
