INTERESTING FACTS

  • Acorns seem to be emergency provisions; on mild winter days these birds catch flying insects.
  • Breeding groups may contain as many as 7 male breeders and 3 females. All breeding males can mate with any and all of the female breeders of the group.
  • The Acorn Woodpecker stores nuts in individually drilled holes in trees called granaries. The acorns are jammed in so tight that even squirrels can’t pry them out. Some of these granary trees have up to 50,000 holes drilled by extended woodpecker families.
  • A group of acorn woodpeckers are collectively known as a "bushel" of woodpeckers.
