Sound Recording: Very soft Cassin's Sparrow

Recorded on Aug. 9, 2019 Recorded in Madera Canyon, Pima County, Arizona

This bird was singing somewhere not too far away, but I had no direction and had trouble getting any clean recordings anyway. Made on my iPhone on a field trip with the Southeastern Arizona Birding Festival; there is lots of noise in the background that I tried to edit out.
