♫542. About an hour before sunrise, the male sings high overhead in an elliptical flight over his chosen nest site, and I do my best to track him with the parabolic microphone. May 23, 2009. William L. Finley National Wildlife Refuge, Corvallis, Oregon. (2:03)
♫543. More dawn singing, this time from the nest site itself. In the background, a great crested flycatcher offers his dawn singing; a song sparrow and common yellowthroat also sing repeatedly. May 17, 2012. Satan's Kingdom Wildlife Management Area, Northfield, Massachusetts. (5:10)
