Species: Fox Sparrow
Passerella iliaca
Description:
Chubby, large
sparrow with variations of coloring from dusky brown to fox red or
slate often so dark that no back pattern can be discernable. There
are considered to be four subspecies due to color variants. All
subspecies have heavy streaking of underparts converging at
midbreast into a larger brown spot.
Identification:
General: The
Fox Sparrow is a large, chunky sparrow and the only member of the
genus Passerella, although some scientists split the genus into four
species or forms. The Sooty form is the one found in south-western
BC breeding along the Pacific Coast and wintering from Alaska to
California.
Fox Sparrows spend much of the time in the shade of shrubs and
bushes using a "double-scratching," backward scratching motion to
uncover insects and seeds in fallen litter. It is widespread
throughout coastal western North America breeding as far north as
the Aleutians.
Larger sparrow,
rounded head outline, heavy bill with lighter-colored lower
mandible, distinguished by slightly notched tail. Color variations
in subspecies, all populations interbreed where range overlaps.

Its vigorous "double-scratching," kicking backward in ground litter
with both feet to uncover food, often draws attention to its
presence under a bird feeder. Sings from elevated perch, gregarious
except when breeding. Nests near ground.
Habitat:
Thickets and forest edges mixed or second growth forests.
Information:
Often mixes with
other sparrows when not in breeding season. Spends much time in the
shade of shrubs and brushes scratching in fallen litter for insects
and seeds.

Populations appear
stable.
