White-headed Woodpecker (Picoides albolarvatus)
…A species of woodpecker that is endemic to western North America, ranging from British Columbia through southern California. White-headed woodpeckers typically inhabit montane coniferous forests which are dominated by pine trees. Like other woodpeckers P. albolarvatus feeds mostly on insects and conifer seeds.
Interestingly, the subspecies P. a. gravirostris has a longer bill and tail than the other subspecies, and it is only found in the San Gabriel Mountains. The longer bill and tail are adaptations to be better able to feed on the large spiny cones of Coulter Pines (Pinus coulteri)
