Woodpecker Holes in Sour Cherry Bush
I saw a Downy Woodpecker pecking at the trunks and branches of a sour cherry bush I have the other day. I went out to see what it was pecking at, and found the hole shown in the centers of the attached picture along with some others. The bush shows no sign of any problems (that I can see), and leafed out and bloomed nicely this year despite being a recent transplant and the drought.
Any comments? Just marking the territory?
