We bought a house a few years ago with a pear tree in the yare. Our pear tree bore fruit this year, but the pears all fell off the tree early in the spring. Also, I don't remember the leaves having so many bright orange spots on them in the past the way they do now. Is this normal?
Many fruit trees abort fruit to naturally thin the crop.
It also could be due to environmental causes, pests and disease.
The leaf spots could be a few different issues, without an image it is difficult to say.
