magnolia tree has rows of small holes in the trunks. I just noticed
it this winter after the leaves dropped. Do you think some kind of
borer is attacking my tree? If so, what can I do about it?
the holes appear in rows, it is more likely that the yellow-bellied
sapsucker (Sphyrapicus varius) is responsible for the holes. These
are medium-sized woodpeckers that have red heads, with white wing
stripes and black crescents on their chests. They feed on sap from
the holes they drill, as well as the insects attracted to the sap.
They feed on over 250 species of trees, including magnolia, elm,
pine, birch, maple and hemlock.
