March 23 Univ. of Calif. campus, Berkeley, Alameda Co., Calif.
As yet, no cliff swallows have
returned to the south side of Life
Sciences Building. A number of last
year's nests are still present, and
appear to be in rather good shape, too.
March 24 Bridge, 10 mi. west, 1[illegible] mi. south of Turlock, Stanis. Co., Calif.
No birds have made their appearance
here as yet. Last year's nests are nearly
all destroyed - a few complete nests
remain. There is plenty of mud close
at hand to build new nests.
Crows Landing Bridge, 8 mi. W., 4 1/2 S. of Turlock, St. Co., Cal.
This bridge is about 2 1/2 miles, airline, from
the previous bridge. However, a large
number of birds are already here.
The majority of the nests look
completed, or nearly so.
April 11 Berkeley campus, Univ. of Calif, Alameda Co., Calif.
Today was the first time I have seen
ciff swallows around the Life Sciences Bldg,
so far this year. There were about 2 dozen
of them circling near the building about
11 A.M. However, when I looked again at
1 P.M. and at 3 P.M., I could see none of them.
Again at 5 P.M., though, I could see 5 or
6 circling near the building.
April 22 Bridge, 10 mi. W., 1[illegible] mi. S. of Turlock, Stanislaus Co., Calif.
Still no swallows using either of these
two bridges for nesting.
