A recognized observer says he has found it only in the woods, and mostly in the luxuriant forests of the bottom lands. The writer's experience accords with that of Audubon and Wilson, the best authorities in their day, but the habits of birds vary greatly with locality, and in other parts of the country, notably in New England, it is very familiar, delighting in the companionship of man. It breeds in eastern North America, and winters in Florida, Cuba and Central America. The Vireo makes a very deep nest, suspended by its upper edge, between the forks of a horizontal branch. The eggs are white, generally with a few reddish brown blotches. All authorities agree as to the great beauty of the nest, though they differ as to its exact location. It is a woodland bird, loving tall trees and running water, "haunting the same places as the Solitary Vireo." During migration the Yellow-throat is seen in orchards and in the trees along side-walks and lawns, mingling his golden colors with the rich green of June leaves. The Vireos, or Greenlets, are like the Warblers in appearance and habits. We have no birds, says Torrey, that are more unsparing of their music; they sing from morning till night, and--some of them, at least--continue theirs till the very end of the season. The song of the Yellow-throat is rather too monotonous and persistent. It is hard sometimes not to get out of patience with its ceasless and noisy iteration of its simple tune; especially if you are doing your utmost to catch the notes of some rarer and more refined songster. This is true also of some other birds, whose occasional silence would add much to their attractiveness. THE MOCKING BIRD. Some bright morning this month, you may hear a Robin's song from a large tree near by. A Red Bird answers him and then the Oriole chimes in. I can see you looking around to find the birds that sing so sweetly. All this time a gay bird sits among the green leaves and laughs at you as you try to find three birds when only one is there. It is the Mocking Bird or Mocker, and it is he who has been fooling you with his song. Nature has given him lots of music and gifted him with the power of imitating the songs of other birds and sounds of other animals. He is certainly the sweetest of our song birds. The English Nightingale alone is his rival. I think, however, if our Mocker could hear the Nightingale's song, he could learn it. The Mocking Bird is another of our Thrushes. By this time you have surely made up your minds that the Thrushes are sweet singers. The Mocker seems to take delight in fooling people. One gentleman while sitting on his porch heard what he thought to be a young bird in distress. He went in the direction of the sound and soon heard the same cry behind him. He turned and went back toward the porch, when he heard it in another direction. Soon he found out that Mr. Mocking Bird had been fooling him, and was flying about from shrub to shrub making that sound.
