P1CID.E — THE WOODPECKERS — PICUS. 



581 



Abundant in tlie Colorado Valley, and sometimes seen on tlie Inislies 

 covering the neigliboring mountains. In habits they are the exact re^jre- 

 sentatives of P. Nuttalli, which they so much resemble. 



The relationships of color between this species and NuttaJli are very- 

 close. The differences are, however, well illustrated by the figures of the 

 head and by the diagram, on the preceding page, of the tails of tiie two.
