about a change. The foregoing lists do not represent the total
number of nests found, only the kinds. The total number to date
is about thirty found. A conservative guess would be that there
are probably about forty nests of all kinds to date on this area
(Lat. 161)
which is about 1 3/4 acres including buildings and roads. (Get
exact acreage, also exact Lat. and Long.)
May 19 At 7:45 I was watching the Lawrence Goldfinches at
their tree and heard a thrasher "scrapping" off to the north
wrot
east on a knoll about 150 yards away. I whistled and called
and the sound ceased. Further calling brought no response, so
mentally
I stopped and called the trial a failure. However this was premature,
for within perhaps two minutes after I ceased calling
(Well, a male Junco eating chicken feed on the terrace by the wid
window 8 feet away. Maybe they are not gone after all.)
Brown-eyes appeared about fifty feet away evidently trying to
locate me as she was scouting about, apparently not seeing me, like
a dog. One call brought her to me on the run and although I
offered her half a dozen worms in the palm of my hand, she took
only one, placed it on the ground, battered it about a bit,
then headed for the nest, running as fast as she could along
the road for perhaps the first hundred feet, then at a point
where the grade changes to a pitch downward toward the nest
she took to the air. By the time I had walked to a point in the
road near the nest, she was out in the road again, repeating the
d
previous performance. I waited, but she did not return, although
she has had nothing to eat, herself, from me this morning. It
is clear that the nestlings have first consideration.
10:30. At exactly 10:00 I placed a chair in the glade about
15 feet from the thrasher nest and sat in it for exactly 20
minutes, in order to see what would develop during a definite
period of time. The chair was in the open, but touching a clump
