Sound Recording: Swainson's Warbler
Recorded on May 4, 2013
Recorded in Little River NWR, Idabel, Oklahoma
Duration: 0′22″
This recording was made on a field trip of the Red Slough Birding Convention. Mia Revels, an ornithologist focused on them in the state, led us right to a singing male! I got the recording with my iPhone as a dozen people crowded near—they stayed quiet long enough to get these songs.
