Zone 7 seems kinda warm for a birch tree (they are northern temperate / sub-arctic trees.) So maybe that's the problem.
Have you seriously disturbed the soil near the tree (eg, rebuilt a driveway or walkway)? Birch trees do not like have their toes stepped on.
Look for D shaped holes in the bark about bb size or just a bit smaller. Be about time for the emergence of bronze birch borers. Are these birch trees planted in the sun? makes them more susceptable.
Mine are doing the same thing, in zone 5.

Birch trees can die of old age. Is it over twenty years old?
Mine are only several years old. They are whitespire birch only about 12' tall. I checked trunk & every branch for those D shaped bb size areas but found nothing. I'm a little concerned about someone mentioning they are not for full sun. When planted, the instructions given were to plant in full sun. Hence they have sun from about 9 am on. No little caterpillers or bugs on the leaves. I'm spraying with a fungicide to see if that will help? Any other ideas?
Thank you for your thoughts.

Good day J. Not seeing a photo of the infected leaves or tree makes it a bit difficult assess the cause. With that said, I would suspect Birch Rust or aphids.

Good luck.
My Birch is probably 9 years old. I will look for D shaped holes, etc. tomorrow in day light. Thanks, Jackie .
I'm in zone 7 too and noticed same problem in the neighborhood. I think it due to the rain here in Charlotte a couple weeks ago. We got
5 inches in about one day and it may have killed off some roots. I've similar problems with red maple but the silver maple is doing better. I've a large oak that leaves on the ends of some branches died off. I think it due to the rain. Hold off the watering and they will likely come back.Thunder
