As his name tells you he is one of a family of Warblers. I told you somewhere else that the Finches are the largest family of birds. Next to them come the Warblers. Turn back now and see how many Warblers have been pictured so far. See if you can tell what things group them as a family. Notice their bills and feet. This bird is usually found in the dense woods, especially where there are streams of water. He is a good singer, and his song is very different from that of any of the other Warblers. I once watched one of these birds--olive-green above and yellow beneath. His mate was on a nest near by and he was entertaining her with his song. He kept it up over two hours, stopping only a few seconds between his songs. When I reached the spot with my field-glass I was attracted by his peculiar song. I don't know how long he had been singing. I stayed and spent two hours with him and he showed no signs of stopping. He may be singing yet. I hope he is. You see him here perched on a granite cliff. I suppose his nest is near by. He makes it of twigs and rootlets, with several thicknesses of leaves. It is neatly lined with fine rootlets and you will always find it on or near the ground. In the September and October number of "BIRDS" you will find several Warblers and Finches. Try to keep track of them and may be you can do as many others have done--tell the names of new birds that come along by their pictures which you have seen in "BIRDS." [Illustration: From col. F. M. Woodruff. KENTUCKY WARBLER.] THE KENTUCKY WARBLER. Between sixty and seventy warblers are described by Davie in his "Nests and Eggs of North American Birds," and the Kentucky Warbler is recognized as one of the most beautiful of the number, in its manners almost the counterpart of the Golden Crowned Thrush (soon to delight the eyes of the readers of BIRDS), though it is altogether a more conspicuous bird, both on account of its brilliant plumage and greater activity, the males being, during the season of nesting, very pugnacious, continually chasing one another about the woods. It lives near the ground, making its artfully concealed nest among the low herbage and feeding in the undergrowth, the male singing from some old log or low bush, his song recalling that of the Cardinal, though much weaker. The ordinary note is a soft _schip_, somewhat like the common call of the Pewee. Considering its great abundance, says an observer, the nest of this charmer is very difficult to find; the female, he thought, must slyly leave the nest at the approach of an intruder, running beneath the herbage until a considerable distance from the nest, when, joined by her mate, the pair by their evident anxiety mislead the stranger as to its location. It has been declared that no group of birds better deserves the epithet "pretty" than the Warblers. Tanagers are splendid, Humming Birds refulgent, others brilliant, gaudy, or magnificent, but Warblers alone are pretty.
