, 1953, D. Watson observed a pair of
chickarees in Prater Canyon. The only other specific record in the files
at the Park is of two seen in a branch of Soda Canyon in late 1956. Jean
Pinkley tells me that chickarees have been observed in 1958 and 1959 at
several other localities from Prater Canyon to the hill at the head of
Navajo Canyon. The extent to which increased observations indicate an
increase in number of chickarees is uncertain, since the amounts of time
spent in the field and the percentage of observations recorded are not
known.

Marmota flaviventris luteola A.H. Howell Yellow-bellied Marmot

Records are available of observations at 14 different places in the Park
and in 19 different years between 1930 and 1960. Approximately
two-thirds of the observations have been on Prater Grade or in upper
Prater Canyon or in upper Morfield Canyon. On the morning of August 24,
1956, Harold Shepherd and I heard the whistle of an animal that he was
certain was a marmot, 2 mi. NNW of Rock Springs at the west rim of
Wetherill Mesa. Mr. Shepherd has worked in areas occupied by marmots for
years in southwestern Colorado. Wetherill Mesa is the locality farthest
west in the Park where marmots are known to occur. They occur as far
south as Cliff Palace.

C.W. Quaintance in reports on the results of his work in 1935 included
the following information:

On February 20 in Prater Canyon Ranger Markley noticed that prairie dogs
were active although about three feet of snow lay on the ground. Between
April 15 and May 15 approximately 500 prairie dogs were in Prater Canyon
above Lower Well; through field glasses 350 were counted. Young were
first noted in Prater Canyon on July 12. Quaintance and Lloyd White had
under observation two bulky nests of the red-tailed hawk in the tops of
tall Douglas firs in side draws of Prater Canyon. Quaintance found near
the rimrock a quarter of a mile from the prairie-dog town the skeletons
of two prairie dogs between a sliver of a dead pinyon branch and the
branch itself. Another skeleton lay on a dead limb fifteen feet from the
ground. A red-tai
