Howell, T.R. 1949 S. v. daggetti 74 Crowder Flat, 5200 ft., 38 mi. NNW of Alturas, Modoc co., Calif. June 10 (cont'd.) 3:01 - B to nest u.r., in. Loud cries from young, 3:05 - B. out, to asp 6 ft away, bill gaping, must be panting. Then to s.d.a, preens. 3:07- B flycatches out across meadow. 3:08- A to nest directly, in, out, across meadow flycatching. 3:13 - B to nest u.r. in, out to asp 6ft away, to branch by nest; A to nest direct now, squawks, B away to this side of meadow A in, out, away. to below nest, taps. 3:16 - to asp 6 ft away, drinks sap. 3:17-B to nest, u.r., in, out, 10 yds away. A saps. is flycatching in the meadow, now away to this side of meadow. 3:20-A to nest from this side meadow directly, in, out, away, 3:27- B to nest, u.r., in. A to nest directly, in; silent. One out, then other out, both away to this side of meadow. I leave. It seems from these observations that there is no slackening of activity even during the hottest part of the day -- and it was hot. The parents visited the nest every 7 minutes at the most, frequently with only 1 or 2 minutes between visits. It is noteworthy that in all cases observed thus far that nest sanitation follows a strict routine pathway if not time. When a bird carries feces out of the nest, it always goes to the same tree and drops them; apparently this is true of both birds, not just one. The other pairs show identical behavior.
