The damage done to the spruce trees can be significant.

An excellent research project on the nature of sapsuckers and their associated damage:

Now as to whether spruce trees are "pine trees" ? No, they are not pine trees.
Not exactly, anyway. https://en.wikipedia.org/wiki/Pinaceae

Trees are generally divided into two very large groups. Angiosperm, and Gymnosperms. These two divisions refer to how the plants grow flower parts and propagate themselves. Most folk don't pay any attention to these distinctions, and just call the Gymnosperms an "evergreen tree" or often just a "pine tree".

Around here, a forum filled with people dedicated to spreading knowledge about trees, we try to avoid these kind of generalizations, which we consider grossly inaccurate.
Yes, your tree is definitely a gymnosperm, a known "evergreen". To us purists, however, that is not at all a pine tree. Perhaps this will help:

If you squint real close at this picture, you will see that Pinus is only a small subset of the gymnosperms, yet closely related to the fir and spruce trees. Look at the dark green text.

So yes, they do look a lot like pine trees to folks that have not yet learned to tell them apart. Keep hanging around here, and you will learn to tell them apart at a glance.
