_Warblers._――The _Summer Yellow Bird_, or _Warbler_, is a brilliant and common species, found in every part of the American continent; he is about five inches in length, with an upper plumage of greenish yellow, and wings and tail deep brown, edged with yellow. He is a lively and familiar bird, and a great ornament to the gardens and orchards. His nest is built with great neatness in the fork of a small shrub. It is composed of flax or tow, strongly twisted round the twigs, and lined with hair and the down of fern. This interesting little bird will feign lameness to draw one from his nest, fluttering feebly along, and looking back to see if he is followed. His notes are few and shrill, hardly deserving the name of a song. There is a very great variety belonging to the family of warblers, of which we can only allude to the _Prairie_, _Hemlock_, _Pine-swamp_, _Blue-mountain_, _Chesnut-sided_, _Mourning_, and _Blue-winged Warbler_. _Ferruginous Thrush._――This is the Brown Thrush or Thrasher of the middle and eastern states, and the French Mocking-Bird of Maryland, Virginia, and the Carolinas. It is the largest of all our thrushes, and is a well-known and distinguished songster, and from the tops of hedge rows, apple or cherry trees, he salutes the opening morning with his charming song, which is loud, emphatical and full of variety. These notes are not imitative, but solely his own. He is an active and vigorous bird, flying generally low from one thicket to another, with his long broad tail spread out like a fan; he has a single note or chuck when you approach his nest. Illustration: Ferruginous Thrush. There is a very numerous variety of thrushes in the states, of which the best known are the _Cat Bird_, _Robin_, _Wood_, _Little_ or _Hermit_, _Wilson’s_, and the _Golden-crowned Thrush_. _Wren._――The _House Wren_, throughout the states, is a well-known and familiar bird, who builds his nest sometimes under the eaves, or in a hollow cherry tree; but most commonly in small boxes fixed on a pole, for his accommodation. He will even put up with an old hat, and if this also is denied him, he will find some hole or crevice, about the house or barn, rather than abandon the dwellings of man. A mower once hung up his coat, under a shed near a barn; two or three days elapsed before he had occasion to put it on; thrusting his arm up the sleeve, he found it completely filled with some rubbish as he expressed it, and on extracting the whole mass, found it to be the nest of a wren, completely finished and lined with a large quantity of feathers. In his retreat he was followed by the forlorn little proprietors, who scolded him with great vehemence, for thus ruining the whole economy of their domestic affairs.
