Howell, T.R. 1949 S.v. daggetti Crowder Flat, 5200ft, 38mi. NNW of Alturas, Modoc Co., Calif June 21 (cont'd.), to right as B out to N, A in. The sun during this observation is shining on the birds' left side as they face the nest; the nest itself is in sun. 9:01- A d. appears from S. to dead top of nest pine, taps. I hear a sqwk, see A leave nest to "disposal" tree.. A third bird appears below the tapper - which is B I can't say. They hitch around, and one chases the other to the Pine, then to disposal tree. 3 birds are in the tree, there is much loud squking and chasing that I cannot follow. One bird leaves to the N. 9:04- A (let us say) to Pine, to nest, in; has winged insect, probably a dragon fly. 9:05- B to nest, sqwks, to right, to left as A out, B in. 9:15- A to nest, sqwks to left as B out, A in. 9:18- A glances out as 2 chickadees work by. I can see A's head working busily just inside the hole - possibly trying to catch flies; or whetting bill, or cleaning entrance. 9:25- B to Pine, usual frequent x-wise perching, to right of nest, to nest, sqwks, just ducks as A out, B in. Now B out to Pine, away. Tattoo from meadow. 9:30 - A to nest, faint sqwk, in; 9:31- A out to disposal tree, back to nest from left side, in. 9:36- B from N, as though to alight in Pine, the fly catches, direct to left of nest, sqwks, A out, B in. 9:39- tapping in nest. 9:50- A to Pine, x-wise, to nest, sqwks, to right, B out, A in. 9:51- A out, I think to disposal tree; back to right of nest, picks around nest at what I guess are flies: 9:52 - A back in. 9:56- B to Pine, x-wise, up to left of nest, sqwks, A out, B in. 10:23- at # 1; 10:24- nrd to nest, feeds, off to W. 10:27- bird to nest from W, feeds twice, off to E, now across to W.
