Downy Woodpecker--Picoides pubescens

Male Downy Woodpecker making a possible nesting cavity. Both male and female visited this site. Usually, it is incorrect to label this as a nesting cavity because woodpeckers roost in holes. In this case, however, with both working on it, the probability is high that they are nesting here. Mystic Bike Trail, Nevada County, California on 10 May 2017.
