觀察細節
First observation at 0627. 15 counted on property. Small groups (up to 20) seen, including both juveniles and adults. Lots of rough, hoarse calls. Later in the survey, 15 or more were perching the chokecherry row south of reach 3, with individuals or small groups flying out and then returning. Suspect that adults were foraging and returning to feed dependent juveniles, but was not able to confirm that. Detections (number 15-minute intervals in which the species was detected): 7 on property. 2 flyover(s).
