Reaction to a dead hawk.
At about 11:30 Mr. Sampson and I went to the glade, the latter
carrying a small Sharpshinned Hawk that he had just shot in his garden.
The thrashers came to the edge of the bushes, but would not come out.
As the wind was still blowing hard, they probably would not have come
out anyway, as just noted; but Brownie plainly showed that he saw
the dead hawk and was nervous about it. I took the hawk to the edge
of the bushes and tried to get the thrashers to come for worms. They
would approach within about 4 or 5 feet of their dead enemy, but no
nearer. The question in my mind was whether their curiosity about
death animals (several times mentioned in these notes) would triumph
over their fear of hawks. The wind, however, introduced a disturbing
factor which made the test inconclusive.
The dead bird was as small as any I have seen of this species;
certainly no larger than Brownie, and perhaps smaller; probably a
young male. A few minutes after this another one was seen just clearing
the tree tops.

Early song. There was some early morning song. At 8 o'clock, judging
by the sound becoming fainter, the thrashers were just leaving the
place on an expedition. In an hour or so they were back again and
the usual scenes were repeated. There was a little carrying of twigs,
but not much.
Black-billed Magpies.
(During the course of the afternoon, a gardener employed at
one of the homes here, brought two Black-billed magpies, whose owner
was leaving the state and wished to have the birds find a good home.
I undertook to look out for them and see that they got it, some place.
They are reported as being taken from the nest last year, east of the
Cascades, near Yakima, Washington).
Feb. 12th.
Full song in distance.
At 8 A.M. full song was heard in the distance. Following up
