chin and bib, and gray cheeks, otherwise dark brown upperparts and light
brown underparts. Females are overall brown with streaked back, unstreaked
breast (unlike female House Finch), and wide,
tan-colored stripe behind the eye.
CALL: a series of one or more chirps.
NATURAL HISTORY: Formerly called English Sparrow, the house sparrow was
purposefully introduced to the United States (for its attractiveness and
for insect pest control) in the mid-1800s, and it took only 50 years to
spread across the U.S. The House Sparrow almost exclusively associates
with humans and their livestock in the U.S. These are the birds that you
see picking up crumbs in parking lots and restaurants. Diet, besides human
garbage, includes blossoms, seeds, fruit, insects, spiders. Will use woodpecker
cavities in saguaros as nest sites.
