The owlets took their beetles with avidity, swallowing them whole and gulping and gagging in the process in a manner indicative of discomfit rather than any satisfaction over the meal. Once the mother brought what in the darkness appeared to be a small mouse, and this too was swallowed by one little owl, but only after heroic and protracted efforts. It was no great matter on the following day to gain the confidence of the young owls to a slight degree. But food was the only bond of affinity. So long as I fed them they were content to perch on my finger, fierce and solemn little ruffians, and devour bits of raw meat. Their manners remained sullen and forbidding, though they never refused to eat. Soon they lost even this slight contact with our world and disappeared into their own--the nocturnal and barbarous world of the owl. Every year there is fresh evidence that the course of true love runs far from smoothly with the birds. A pair of yellow-throated vireos built no less than three nests one season and only succeeded in occupying the last. There were two suitors for the affection of the female, and they fought continually. The rejected lover harassed the pair while at work gathering material, and that he twice stole a march on them and actually tore down the nest appears from circumstantial evidence. Great secrecy was observed in constructing the third nest, and the rejected one no longer harassed them. Either he had transferred his affections or been fairly vanquished. Life was strenuous and impassioned with these little birds, but see what constancy and perseverance! Fancy having two houses torn down, after completing them with your own hands, and having the courage to build still a third! There is something of the pioneer and frontiersman in this. The offspring of this pair were the children of vigorous and romantic times, and should have inherited some heroic traits. Even if all goes well otherwise, the sanctity of the nest is liable to be profaned by the cowbird. This spring was an unusually favorable one for them. I noticed the least flycatcher and the Maryland yellow-throat mothering young cowbirds, and many vireos and warblers so engaged. It is a wary caution that leads the cowbird to choose the smaller birds for her victims. It would be hard to say which of all the foster-mothers is the more solicitous of her charge. Now it appears to be the redeye, and again the chipping-sparrow. All alike are bent on bringing the birdling to maturity as though it were of first importance. _That_ cowbird shall thrive though the heavens fall. The attention seems to be in proportion to the egregious demands of the foundling. Here at least is a waif well cared for, an upstart that takes precedence over the true and lawful heirs. Another year this same adventuress will invade the nests of her adopted sisters.
