I’ve never seen such a pattern of squares pecked or eaten into tree bark.

We planted a couple pine trees in the backyard, and despite their being snowbent, they seemed to be thriving. However, a close look reveals networks of holes in the bark, on the main trunk, directly underneath each spray of branches. Who or what is doing this? Birds? Insects? I’ve never seen such a pattern of squares pecked or eaten into tree bark. I guess this will eventually kill them, but so far this year, they are green and growing.
Edit: In the final pictures in the slideshow below, you will see the holes have mostly healed.
