Swallow songs

Barn Swallow dawn song, consisting of mostly three part phrases, 50 minutes before sunrise, by a bird flying to and fro over a meadow. The song finished well before sunrise. (June, PA).






















Tree Swallow dawn song perched (5.48am, May, NJ)

Tree Swallow dawn song in flight (4.50 am, June, CO).











Violet-green Swallow dawn song for comparison (in flight, 4.45am, June, CO)












The Tree Swallow day song is more varied than the more stereotyped dawn song, bird in flight (May, RI).

tinkling calls are reminiscent of Sprague's Pipit








buzzy calls









chirps
