Yesterday I recorded an as yet unidentified bird singing along the Indian
Creek Trail between the College Park Airport and Lake Artemesia.

The bird sings twice during the clip, once at around 14 seconds, the second
time at 32 secs (sorry for my mumbling in the background):

Thanks in advance to anyone who can help!

Good birding,
