What kind of trees are these? Pear

SE Iowa. What kind of trees are these?

My guess is pears but that's solely based on their growth habit.

I concur with Mike. White flowers are typical of pears. Are the leaves smooth, almost glossy?

I'd say they look like pears to me based on the flowers and leaf shape

Leaves look very similar to my persimmons

Bradford Pear.  They are invasive in my area.  They also are weak trees due to the crotch angle of the branches which leads to bark inclusion.
