Hello Connie,If you look at the 1st picture you will see holes in the shape of a sideways D.  That is a symptom of bronze birch borer.  Can you send me a picture of the whole tree from top to bottom?  Please, send to <personal data hidden>Thank you,

That's what I was afraid of. The diseased tree is the one in the middle.
