We also have a neighborhood pair that stop in several times each spring.
When not plopping down in our pond for a quick swim, they wander about
the area, visiting front and back yards, eating bugs, slugs and snails.

This will be like the 4th year the same pair (AFAIK) has come back.
They nest at the local park district pond, but come here to feed in the
spring.
