June 23 (cont'd.) - 11:47 at #8 - d. near nest, in same tree, leaves at
my approach. 11:50 - d>n to nest, feeds, off. 11:54 - d. to nest; 2 feeds,
to small asp 10 yds away, sits, off to S. 12:00 d. to nest again,
2 feeds, to big pine near me, 20yds away, looks at me
curiously. 12:02 d>n to nest, 2 feeds, to another pine above
me. Now d. to nest again, feeds, d>n screams several
times, d. away from nest, over towards d>n. I leave.

The young in #8 are about 18 days old, typically noisy.
12:13- at #6 - d. to nest, in, wren hits at disappearing tail.
d. out with debris, to usual pine, then to asp, by it, feeds

12:16 d from E, 2 feeds, to same asp, seems to eat sap, picks

off to E. 12:28 - d. from E, flies by with squks to feeding asp;
d>n up right behind d. D. picks a moment, then to nest,
in slowly - wren hits at tail - out, off to E. 12:30 d. from
E, 1 feed, in, cleans nest, then to feeding asp, picks at holes,
off to W, back to asp, , to E; squks; 12:33 d>n to right
opposite nest, 2 screams around to nest scream, looks or

nest. 12:35 - d. from E, in, cleans nest again. I now go up and
look in - the young fit the description of those in #1 on the 20th.
