SONG-BIRDS.

Mourning Warbler: Geothlypis philadelphia.

Length: 6.25-5,50 inches.

Nest and Eggs: Like those of the Maryland Yellow throat.
Range: Eastern North America to the Plains; Central America and northern South America in winter.

The Mourning Warbler is seen here only as a migrant, but its appearance is so marked that it deserves mention even when others of the same genus of equal rarity, but of less distinetive plumage, are omitted. Dr. Coues refers to it as resembling in its appearance and behaviour a gay and agreeable widow, who is conscious that her weeds are becom-ing. Its general habits, like its song, somewhat resemble those of the Maryland Yellow-throat, but though a Ground Warbler, nesting and spending much time in the bushes and tangles, it does its most vigorous singing in the tree-tops of woods where the underbrush has been left undisturbed.

Burroughs says: "The Ground Warblers all have one notable feature, — very beautiful legs, as white and delicate as if they had always worn silk stockings and satin slippers. High Tree Warblers have dark brown or black legs and more brilliant plumage, but less musical ability."

Maryland Yellow-throat: Geothlypis trichas.
