NOTES: Unusual vocalization.
Male singing from exposed perch in oat field. Song perch is a thistle plant sticking above the surrounding vegataion. Squeal call accompanied by wing lifting posture.
[There appear to be nine songs from the closer bird, with others from a second individual in the background. Also given were six dry "chek" or "pwik" calls (0:08, 0:11, 0:15, 0:19, 0:24, and 0:35) and an odd "rattle" that is not described in BNA (0:22). Quality changed from 1 to 1-2 - CAM - 31 January 2005]
