I am not sure about the identification of this bird but I think it’s a Common Yellow Throat Warbler.
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.
