length. This species is indigenous to the eastern and 

 southeastern sections. 



The more common species (Sciurus n'lger rufi- 

 ventcr) is not so large as the one above and is less 

 variable in coloration. The ears and nose are never 

 white. The under parts are always rufous yellow. This 

 species has a total length of about twenty-three inches. 

 It feeds on nuts, seeds, birds and fruit. 



The yellow bellied fox squirrel is well distrib- 

 uted in western Pennsylvania, but it is not at all com- 

 mon. 



Red Squirrel (Southern) 



Sciurus hudsonicus loquax 



The red squirrel is the sauciest, most active and 

 most curious of the Pennsylvania squirrel group. 

 There are many species of red squirrels, and the num- 

 ber in the State is a matter of some controversy. Inas- 

 much as there is a wide variation in the color of the 

 pelage of even a single species, it is difficult to deter- 

 mine whether some of them, are true species, sub- 

 species, or only varieties. There are three possible spe- 

 cies within the confines of the State. The assumption 

 is based on our knowledge of the geographical distri- 

 bution of the various kinds. The three that may possibly 

 exist here are: The eastern red squirrel, or chicka- 

 ree (Sciurus hudsonicus husonicus), the southern red 

 squirrel (Sciurus hudsonicus loquax), and the little 

 red squirrel (Sciurus hudsonicus gymnicus). The 

 first is supposed to be confined to the Canadian section 

 but it seems to have migrated southward and is re- 

 ported from the north central counties of Pennsylvania. 

 The second is supposed to be the commonest species
