Seven Devils Mtns, Idaho Co., Idaho (cont.)
From the NE wall of HeDevil. At 4:00pm an adult chirped in series of 1, 2, or 3 chirps & flicked its tail with many of the chirps; all from a rock outcrop 100yds away from me. Then it flew to a tree near to me and chirped briefly, then back near the original location, but this time perched in a snag. At 4:06 PM it flew to the nest & fed the screaming young. I then moved to where I could see this location better. At 4:14pm both adults arrived near the nest. One (?) chirped a few times, then they both flew to the nest. The young chirped, then stopped. One (dark colored) bird flew in a glide from the nest. Shortly the other flew out and landed on a rock at which time it was aware of my presence. Perhaps it flew from the nest because of my presence. I collected it (? with brood patch and full buccal pouches). The full pouches suggests that it hadn't fed young yet & that I may have disturbed it. In the interval after this & prior to the next feeding (by the one remaining adult) the young became increasingly noisy. Their voices are less husky than those of adults but still quite well developed. At 5:43 pm The adult returned & quickly fed the now vigorously screaming young & left with a fecal sac. I was unable to collect
