Bird Species Censuses In Crater Lake National Park
By Ralph R. Huestis, Ranger Naturalist, 1937
Check lists of bird species in specific areas are indispensable to
the scientific investigator but not much use to the average tourist who
is interested in birds. The tourist may be impressed with the richness
of the display on paper, which many years of investigation on the part
of a number of observers has accumulated, but what he would like to know
is, "What birds am I likely to see in a given locality if I go there
during a certain season of the year".
To fill this need a few bird census reports have been made of some
of the areas in Crater Lake National Park which are readily accessible
to tourists who may wish to study birds. Vernacular names for the
observed species are used and they are written in the order in which the
birds were encountered.

It may be seen from the above lists that certain birds like the
Siskins, Juncos, Audubon's Warblers, Chickadees, Chipping Sparrows, and
Olive-sided Flycatchers are widely distributed in the park. The lists
explain too, why many tourists comment on the poverty of bird life in
the park. Tourists spend most of their time along the rim where
possibly because of the ubiquity of the Clark's Nutcrackers, very few
species are to be found. At elevations lower than the rim, especially
in the well watered valleys, twice as many species may easily be
observed.
