Downy Woodpecker Trap Door

Downywoodpecker “trap door” and claw marks on a white birch.” (Mono Cliffs Provincial Park, May 2014)

“A coccid species (Xylococcus betulae) often spends the winter in the space just under the outer bark of a white or yellow birch tree.  The downy woodpeckers peck and cut a vertical line in the outer bark next to the coccid and they pry up the bark to expose and eat the insect.” (Bird Tracks and Sign* p 258).
