In May, L887, a smart contest between a pair of red-backed juncos 

 and an Abert squirrel was witnessed near Mormon Lake, and I have 

 also seen fierce attacks made upon this squirrel by infuriated long- 

 crested jays, whose jealousy of intrusions about their premises is 

 always conspicuous. The Mexican woodpecker and Abert squirrel 

 have unending and vociferous quarrels and feuds over the latter's 

 propensity for pilfering from the hoards of nuts stored in the pine 

 hark by the busy woodpecker, and -cold, berate, and belabor each 

 other soundly. 



The Abert pine squirrel is very plentiful in Bill Williams Moun- 

 tain. Arizona. 



Measurements of 29 specimens of Sciurus aoerti.
