Howell, T.R. 1949 S.v. daggetti Crowder Flat, 5200ft, 38mi. NNW of Alturas, Modoc Co., Calif. June 30 (cont'd) a dead asp 40 yds N; more screams, to W, back, more screams; away 11:25. 11:26- d, NE, 2, above nest - ?. 11:28 d, same, W, as down, squks, W, 1, NW. 11:30 - n., N, gives what I can only call sqwk-screams, 1, looks around, sqwk-scr., branch, NW. 11:30.5 d, ?, 1, above nest, taps. 11:34 - n, NW, screaming, to d,, squiks, n. to nest, 1, looks around, NW. 11:37- n., NW, 2, NW. 11:40- I leave. For the first time that I can recall, there was a 16min. gap on the feeding - 10:45 to 11:01 - and n. was away for 32 minutes. It could easily have been n., therefore, that I saw near Twin Spring yesterday. Also, n. seemed nervous, and was very noisy. 1:00 P.M., at #12. Between 1:00 and 1:12, the young were fed 3 times, twice by d,, and then by down. on the 2nd time d went in the nest and came out with debris, gliding over to a nearby pine to drop it as before. I saw both parents at the nest together, with the usual squks. The young were cheeping, and I could see a head out occasionally: these young must be at least 23-24 days old. 1:20 - at #14, at Twin spring. A d,, not down, to nest; goes in, out to a pine 15 yds away, probably cleaning nest. 1:22 - d. back to nest, hitching up from below, in; out again with debris, to a different pine in the opposite direction. The young are cheeping, and a head is usually out. Those also look at least 23 or 24 days old. This pair then, is d. x down. 1:40 - to #3; I climb and look in; all I can see is a mass of ants on the bottom feeding on excrement. Nevertheless, B comes up and screams from N. asps.
