June 27(cont'd): 3:45 P.M. - at #8 for a brief watch. I was seen by dsn, and the bird screamed loud and long. Finally I got out of sight and watched. Between 3:45 and 3:58, dsn made 2 visits to the nest and d. also 2 visits. The young had a head out most of the time, and I heard a few imm. screams. These are about the same age as #1 and #3, or about 24 days.
4:05 P.M. at #1. 4:06- nd to left of nest, not to it, looks, flies over just over my head, then to W. Silent. I am 20yds to the NW. Young very noisy, heads in and out. Some imm. screams, mostly harsh cheeps. 4:12- from W, I feed, to W. 4:16- from W, I feed, to N asps, to S, asps, to E. 4:17- across to W. 4:18- from W, I feed, to 10 yds W, out of sight to W.
4:28 - from W, I feed, to NE. Young noisier than just before feeding, few "screams" 4:30- from E, I feed, to W. 4:31- from W to N asp, to nest, I feed to hungier, to E. 4:32 from E, I feed, to E. 4:33.5- same. 4:35- across to W. 4:36- from W. to#1 feed, to N asp, to E. 4:45- from W, 2 feeds, to W. 4:49- from W, I feed, to W. 4:51.5- from W, 2 feeds, to N asp, to W. 4:55 same as 4:49. 4:58 - from W, I feed, to N asp, to SE, around to SW
5:00 P.M., I leave.
The noteworthy features today are the fact that the young have their heads out (one bird at a time) most of the time, and that they are starting to make more adult noises, i.e., screams. The parents seem a bit more nervous, and in some cases (#1) feeding seems to have slowed a little. I don't think #s 1,3, and 8 will stay in the nest much longer- there can't be much room, in fact. Both parents are active at all nests except #1 of those checked today.
