What are these, and do deer eat them?
Looks a lot like callery (bradford) pearMaybe Bradford pear. In many places they are taking over the landscape.
I have no idea on those.
Could you get a pic of the leaves and bark maybe?
I think that's some variation of the Bradford pear. Deer will probably eat them as they're passing thru.
Did you taste one and see if it tasted sweet, like a pear?
