on agave hillsides, where they live in closest association with the
intermedia wood rats.

6643 Black-Tailed Gnatcatcher (female sign) ad. 5.8g. Shot in
artemesia californica (?) bush.
6644 Western Gnatcatcher (male sign) ad. 5.6g. Shot in sumach bush.

Barometer tonight 29.85 inches; warm, muggy;
high fog all day. One perspires too freely for comfort.
7 p.m. - Writing by light of of burning agaves- dead
ones, of which there are many on the hillside above
our camp. Just went the rounds of my
traps by flash light - one Perognathus and one Peromyscus,
only, so far. Had re-set Dipodomys traps at
fresh burrows, but untouched; maybe these rats do
not come out so early, altho it was quite dark
by 5:30. Saw a Black Phoebe late this evening. The
Western Gnatcatcher taken is the only one of that species
so far noted here. The Black-Tailed Gnatcatcher is
fairly common, but I find them hard to see by reason
of their dark colors, much harder than the other
species. The black-tails keep nearer the ground, among
the dark stems in the thick brush-clumps. They
have two kinds of notes, the faint nasal mew,
and a louder, repeated che-che-che-che; so I was
right (p. 2593).

Discarded: Peromyscus m. gambeli, (female sign) (4 emb.), 2 small blue-

Same trap as yesterday’s.
