The morning sky is again held up with sound. Winter’s cruel quiet a mix of breath and stars has given way to a small but hardy morning chorus of bird song. Birds like the Red-winged blackbird have returned to Southern New England and joined the songs of the Northern Cardinal and Tufted titmouse. The east coast awaits a May deluge of southern migrants making these mornings a good time to learn the songs of the more common birds. Listen in particular for the “laser tag” blasts of the Northern cardinal and the “peter-peter” of the Tufted titmouse. Birds sing for many reasons and spring is the time for both courtship and nest site selection and singing males are most likely working both angles although the Northern cardinal represents one of a few North American female songsters.
