higher, flying when they saw me, one of them carrying a dead bird
in its claws which I could not identify.
B stubborn
in nest. Brownie was still in the nest, tail toward me. He would not
turn around to get the proffered worm, so I left him. He would not
come down to eat either, and G did not appear.
At 10:00 B was still in the nest, but had changed position 90
degrees, so that I could hold the worm right in front of his bill.
However, he would not take it, nor would he come down to eat, nor
could anything be seen or heard of his mate. I began to wonder if
G might not have been the hawk's victim, so went in search of her.
She was in the orchard. I returned to the glade. G came in a few
of the new cycle.
First egg.
7 days earlier than last
year. minutes, and at 10:30, they changed shifts, revealing the first egg.
B then came and had a good meal of worms, notwithstanding his in-
difference while in the nest.
The first egg last year was laid on Mar. 8th., so the present
one was laid 7 days earlier. If it had been a day sooner it would
have been a February egg and would "sound" a month earlier.
The advent of this egg was not heralded by loud song and both
birds have been almost completely silent all day, in contrast to
behavior in connection with nest NO.5.
At 5:30 P.M., the first observation for several hours, B was in
the nest, apparently quite pleased to have me hand him worms. At
5:40 G took over, B coming to me for more worms and having a good
stretch, arching his back like a cat.
March 2nd.
B fearful of
hawks. At 8:30 A.M. Greenie was in the nest, Brownie, fearful of hawks,
came skipping and hopping for worms, only to dart back again after
each one with keen glances up into the sky. There were new feathers
near the feed dishes, and a hawk raid was heard earlier. The in-
creased activity of the hawks in the morning may possibly act as a
damper on the thrasher music.
No demonstration
for first egg.
