Common Yellowthroat Warbler (Geothlypis trichas)

I am unsure about the identification of this bird but I think it's a Common Yellowthroat (Geothlypis trichas).

Abundant and well-known, the Common Yellowthroat has succeeded by being a nonconformist. As the only one of our warblers that will nest in open marshes, it is found in practically every reed bed and patch of cattails from coast to coast. Although it sometimes hides in the marsh, its low rough call note will reveal its presence. The male often perches atop a tall stalk to rap out his distinctive song, wichity-wichity-wichity.
