Downy Woodpecker - Picoides pubescens

Downy Woodpeckers are generally easy to sex; ageing can be somewhat more complex because individuals can typically be aged to at least ATY, but usually is possible by looking closely at the primary coverts.

Note that because woodpeckers tend to have an incomplete prebasic molt, appearance may differ before/after the molt, even though the same age (e.g., SY) can be determined, therefore identifying whether molt has occurred is important.

Quick Tips:

  • Check the head for red feathers - only juveniles have any on top of the crown (extensive in males, limited to absent in females); otherwise only males have a small spot on the hindcrown.
  • Carefully examine the primary coverts, with a focus on retained brownish juvenile feathers. They are uniformly paler than adjacent tracts until the second fall (HY/SY), then the outermost primary coverts are contrastingly black until the following fall (SY/TY), after which they usually are uniformly black or a mix of black and blackish (ASY/ATY)
  • In summer to early fall, check the length of p10 - in juveniles only it extends >7 mm beyond the primary coverts
