When he lives west of the Mississippi River he is called the Western Yellow-throat. A Tree Trapper and occasionally a Sky Sweeper; a beautiful and familiar bird of the brush and tangles. THE YELLOW-BREASTED CHAT "The Chat, besides being a very handsome bird, is a ventriloquist and a great joker." "Please, Uncle Roy, what is a ventroquist?" asked Dodo. "I should have remembered not to use such a long word," laughed the Doctor. "A ven-tril-o-quist is a person who can not only imitate sounds, but makes it seem as if they came from his stomach, or even in a different direction from where he is himself. The Mockingbird can imitate many sounds, but all these come directly from the bird; while the Chat can perch on a twig above your head and give a whistle that seems to come from a bush across the road. "This is what enables him to play tricks on birds, House People, and various other animals. He will whistle until he has set a dog tearing through the bushes to find his supposed master. Another time he will give such a soft strange series of notes that a bird-lover will immediately begin to search through a tangle of briers, after what he imagines to be a strange bird. Then he indulges in a fit of merriment at his own jokes--'chatter-chatter-chat-chat-chat-chat-chat' he says, calling his own name as he slips away to the security of a catbrier or barberry bush. Large and vigorous and strong of beak as he is, this practical joker is wise, and does not often show his conspicuous yellow breast in open places. [Illustration: Yellow-Breasted Chat.] "Some day in the nesting season you may see the Chat fly up in the air and hear him sing his courting song, which is very sweet, different from all his jests and jeers. You will say, if you are near enough to take a long look--'Why, that Chat has forgotten to fold up his legs, they are hanging straight down.' He has not forgotten, however; it is merely one of his odd habits at this season to cut all sorts of capers in the air, with his legs and wings and tail let loose, while his mate is quietly house-keeping in some thick bush near by. The nest is something like a Catbird's, not very tidy outside, but snug inside, and easy to find if you look in the right place. If you find it at the right time you will see that it holds four or five well-rounded eggs of a crystal-white color, with plenty of bright reddish-brown spots all over them." The Yellow-breasted Chat Length seven and a half inches--much more than any other Warbler measures. Upper parts bright olive-green, even all over. Lower parts very bright yellow on the throat, breast, and wing-linings, but the belly pure white. A strong dark-colored beak, with some dark and light marks between it and the eyes. A Summer Citizen of the United States east of the plains and south of Ontario and Minnesota; travels far south in winter. When he is found west of the plains his tail is somewhat longer, and he is called the Long-tailed Chat.
