♫383. By day, a repeated pit-TSEEeeuur, distinctively down-slurred and instantly recognizable, and after several renditions of that song he seems to ask the question, prrrREEP, rising and raspy. May 27, 2009. Oxbow, Hells Canyon, Oregon. (2:10)
♫384. During the energized dawn chorus, the male adds a third song, a rising pit-urr-EE-EEP. The first five songs here are as follows: pit-TSEEeeuur . . . pit-TSEEeeuur . . . prrrREEP. . . pit-TSEEeeuur . . . pit-urr-EE-EEP. Close your eyes—transport yourself there, to this bird mecca in southeast Oregon, identifying each of this phoebe's songs as he delivers it. Enjoy calls and dive displays of the common nighthawks in the background. June 10, 2009. Malheur National Wildlife Refuge, Burns, Oregon. (2:40)
♫385. Just after sunrise, the dawn chorus largely finished, this male continues to use his three different songs, but with far less vigor. March 24, 2017, ten minutes after sunrise. Smoke Tree Canyon, Anza-Borrego Desert State Park, Borrego Springs, California. (4:38)
