Is this is a black birch tree?

I'm trying to get more into tree identification.
I went hiking out in the woods the other day and saw a bunch of these and was curious as to what they were.
I don't have any leave photos to show because all the leaves have fallen off the trees here now and area all mixed and scattered about on the ground.
I'm in Connecticut.
I know there's a plant id section to this forum.
I thought it was more appropriate to post in the tree section.
Can you guys help me out with an id with some tree bark pictures?
