holes in my two trees

I have these holes in my trees they are 1/16 or an 1/8 inch in dia. almost like someone drilled the holes. These holes are scattered thoughout the trees. Example, they start mostly over a 5′ from the ground. Some holes are in a group others may be one hole or a couple holes. I don’t see any bugs but last season there were some odd looking bugs in the trees and I didn’t think anything of it. Now before we go any further, I’ve got no idea what type of tree they are! The city of Chicago planted them. Any help will be much appreciated.
Thank You,
Steve Szumacher

Dear Steve:
If the holes are in straight horizontal or vertical rows, the holes were caused by yellow bellied sapsuckers which migrate through the area. Unfortunately there isn’t much you can do about them. To discourage sapsuckers from feeding on a favorite tree, wrap hardware cloth or burlap around the area being damaged, or smear the bark with a commercial sticky repellent, such as “Bird Tanglefoot”. Beware, however, that other birds not responsible for the damage can also get stuck in it.
If the holes are not in straight lines, you may have wood-boring insects. Generally, borers are attracted to stressed trees, that is, young transplants, poorly sited plants or plants that are not cared for.
