Oklahoma Winter Bird Profile: Swamp Sparrow




pete-pete-pete-pete-pete, chip! or  Zeeeeeeee!

Common at pond edges or in wet marshes around cattails, shrubs, prairies, salt marshes, or grass, the Swamp Sparrow can be found in old fields or other wet areas during times of migration.  They will mix with the Song Sparrow, and usually stay low under thick cover.  Do not expect this bird at your feeders, though stranger things have happened.

The throat is usually unstreaked and there are blurred streaks upon the buffy gray breast, and a light belly with solid rufous wing coverts.  Even though it has a red crown, its bulky build should not suggest a Chipping Sparrow, as it rarely comes out in the open and stays within a different habitat.  Remember GISS, general impression, shape, and size as a rule for sparrows.  Also note that is has gray cheeks and eyebrows, another defining characteristic from the chippie.  Northern and western birds are lighter in color than the eastern and southern birds.

These songbirds breed in boreal Canada, as well as northern and eastern parts of the US.  Wintering in the eastern part of the country, they make their way to Oklahoma frequently, as well as south to Mexico.

If one is able to photograph the bird, note its longer legs than most sparrows.  This enables it to forage in shallow water.  They usually begin their song early in the day and can even be heard during a nicely moonlit night.

Numbers have been declining in parts of its range, naturally due to loss of habitat, as well as degradation and ill health of its favored waterways.

This bird will clearly be expanding north in its ranges, most notably for winter limits.
