A young farmer in the western part of New York sends me ... some interesting observations about the cuckoo. He says a large gooseberry-bush, standing in the border of an old hedge-row in the midst of the open fields, and not far from his house, was occupied by a pair of cuckoos for two seasons in succession; and after an interval of a year, for two seasons more. This gave him a good chance to observe them. He says the mother-bird lays a single egg and sits upon it a number of days before laying the second, so that he has seen one young bird nearly grown, a second just hatched, and a whole egg all in the nest at once. "So far as I have seen, this is the settled practice,--the young leaving the nest one at a time, to the number of six or eight. The young have quite the look of the young of the dove in many respects. When nearly grown they are covered with long blue pin-feathers as long as darning needles, without a bit of plumage on them. They part on the back and hang down on each side by their own weight. With its curious feathers and misshapen body the young bird is anything but handsome. They never open their mouths when approached, as many young birds do, but sit perfectly still, hardly moving when touched." He also notes the unnatural indifference of the mother-bird when her nest and young are approached. She makes no sound, but sits quietly on a near branch in apparent perfect unconcern. These observations, together with the fact that the egg of the cuckoo is occasionally found in the nest of other birds, raise the inquiry whether our bird is slowly relapsing into the habit of the European species, which always foists its egg upon other birds; or whether on the other hand it be not mending its manners in this respect. It has but little to unlearn or forget in the one case, but great progress to make in the other. How far is its rudimentary nest--a mere platform of coarse twigs and dry stalks of weeds--from the deep, compact, finely woven and finely modeled nest of the goldfinch or kingbird, and what a gulf between its indifference toward its young and their solicitude! Its irregular manner of laying also seems better suited to a parasite like our cow-bird, or the European cuckoo, than to a regular nest-builder.
