American
Tree Sparrow
Though the North American winter resident known
as the American Tree Sparrow looks much like the
North American breeding season's Chipping
Sparrow, there is, in fact, little overlap in the
occurrence of these two birds. The first American
Tree Sparrows typically arrive in late October,
and within a week, Chipping Sparrows depart.
Conversely, American Tree Sparrows depart in late
March, within a week of the Chipping Sparrow's
arrival. As a result, it is rare to see American
Tree Sparrows and Chipping Sparrows in the same
location.
American
Tree Sparrow Range Map
American Tree Sparrows are approximately 6 inches
(15 centimeters) in length. A large sparrow with
a long tail and a rufous cap, American Tree
Sparrows have an unmistakable characteristic: a
dark spot in the center of their breast, and
frosty edges to their wings and tail.
The crown and post ocular stripe are rufous in
color, and the supercilium, cheeks, throat, and
nape are gray. A distinctive rufous-colored comma
extends from the bend of the wing into the gray
breast, which also sports the characteristic deep
brown spot in the center. The flanks of an
American Tree Sparrow have a variable buff wash,
whereas the belly is gray. The back is rusty
brown with dark streaks, the scapulars are
darkish brown with even darker centers, and the
"tertials" and secondaries have frosty
edges that create a characteristic edged look.
The outermost outer tail feathers are pale and
dusky with a thin outer vane approaching white.
The next one in is a darker brown, but a shade
paler than the rest of the rectrices. From below,
however, all tail feathers are the same color.
The upper mandible, legs, and feet are dark; the
lower mandible is predominantly yellow.
