Additionally, the "Lincoln's Sparrow's" upper breast has a buff band, finely streaked with black; his back is buffy-olive and also streaked. Resembling the "Song Sparrow" in looks and manners, this illusive bird is seldom seen in migration. The bird sculks through brushy bogs and willow and alder thickets. A squeaking sound may lure it from cover. Audubon named this sparrow, which he first spotted in Quebec, in honor of his companion on his trip to Labrador, Thomas Lincoln.
"The "Lincoln's Sparrow" breeds from Alaska across Canada, and south to California and northern New England.
Calls or song.
Only the male "Lincoln's Sparrow" sings a rich, warbling song, which sounds like "churr-churr-churr-wee-wee-wee-wah-wah".
Population and distribution.
The "Lincoln's Sparrow" winters in the southern half of the United States.
They build grassy wells, on the ground or in a tussock of forest undergrowth. Here are laid 4 or 5 pale green eggs, heavily spotted with brown.
