"Kak, k-kuh, k-kuk, k-kuk!" like an exaggerated tree-toad's rattle, is a sound that, when first heard, makes you rush out of doors instantly to "name" the bird. Look for him in the depths of the tall shrubbery or low trees, near running water, if there is any in the neighborhood, and if you are more fortunate than most people, you will presently become acquainted with the yellow-billed cuckoo. When seen perching at a little distance, his large, slim body, grayish brown, with olive tints above and whitish below, can scarcely be distinguished from that of the black-billed species. It is not until you get close enough to note the yellow bill, reddish-brown wings, and black tail feathers with their white "thumb-nail" marks, that you know which cuckoo you are watching. In repose the bird looks dazed or stupid, but as it darts about among the trees after insects, noiselessly slipping to another one that promises better results, and hopping along the limbs after performing a series of beautiful evolutions among the branches as it hunts for its favorite "tent caterpillars," it appears what it really is: an unusually active, graceful, intelligent bird.
