Status A local and uncommon wintering species in Maryland. Most consistently found in western Maryland and increasing rare as one moves east onto the coastal plain. Rare in southern Maryland and on the lower Eastern Shore. Snow often increases detectability and sightings at bird feeders.
American Tree Sparrows are generally uncommon winter residents in Maryland - most common in western Maryland and far less common to rare on the coastal plain. Like many sparrows, they can suddenly seem much more common when it snows and they concentrate at roadsides and feeders. They breed across the tundra in Canada and Alaska and are purely winter residents across the Lower 48.

Species of bird
American tree sparrow in Central Park
The American tree sparrow (Spizelloides arborea ), also known as the winter sparrow ,[ 2] is a medium-sized New World sparrow .
It had been classified under the genus Spizella , but multilocus molecular evidence suggested placement in its own genus.
Measurements :[ 3]
Length : 5.5 in (14 cm)
Weight : 0.5-1.0 oz (13-28 g)
Wingspan : 9.4 in (24 cm)
Adults have a rusty cap and grey underparts with a small dark spot on the breast. They have a rusty back with lighter stripes, brown wings with white bars and a slim tail. Their face is grey with a rusty line through the eye. Their flanks are splashed with light brown. They are similar in appearance to the chipping sparrow .
Distribution and habitat [ edit ]
Their breeding habitat is tundra or the northern limits of the boreal forest in Alaska and northern Canada . They nest on the ground. American tree sparrows migrate into southern Canada and the United States to spend the winter.
These birds forage on the ground or in low bushes, often in flocks when not nesting. They mainly eat seeds and insects , but also eat some berries . They are commonly seen near feeders with dark-eyed juncos .
This bird's song is a sweet high warble descending in pitch and becoming buzzy near the finish.
