sites. In one place there were a number of California woodpeckers’ holes in a tall

The following is a list of the land birds that were identified. The sea-birds, 
waders and ducks are not incorporated in this list because those that were identi- 
fied were not particularly noteworthy and because the identification of several 
species was unsatisfactory.

abundantly in 1905 and 1906, when the rainfall was copious.
