The trees in your photo look like birch, so I'm not sure what to make of your question.

Yes the tree in the background is a birch. Thank you. That is NOT the focus of my inquiry. The picture sent is a branch on my ornamental crab tree, just as I had explained.
I will try an arborist in the private sector.
The branch in the foreground is very blurry. It might have a fungal infection such as apple scab. I don’t see signs of fireblight, which is very distinctive. Before you talk to an arborist, you can acquaint yourself with fireblight here:
