Brown toucan, Brown thrasher, valley-
guail, California jay, green-backed
goldfinch, mourning dove, turkey buzzard,
wren-tit, plain titmouse. The guails are very

the stream bed. This morning I found
3 Peromyscus truei and 1 Perognathus c.
in my traps, a very poor percentage.
A thorough poisoning campaign carried
on by the landowners themselves against
rodents two years ago probably reduced
their number of small native animals
to a low level. Woodrats, once fairly
abundant here are now seldom, if ever,
