MAMMALS OF THE MEXICAN BOUNDARY. 



255 



In May, 1887, a smart contest between a pair of red-backed j uncos 

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

 also seen fierce attaclcs 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 

 bark by the busy woodpecker, and scold, berate, and belabor each 

 other soundly. 



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

 tain, Arizona.
