One of the 1st things I noticed when we moved to our town was "geese on the roof"!
I grew up much closer to corn fields than any buildings over 4 stories tall. After getting married we bought this house in the suburbs. During our 1st week I spotted a duck on our roof & the next week a goose on our neighbor's roof! DH didn't believe me & said I was crazy. Back then our house had a swimming pool, so we had several waterfowl visitors. They can fly, so why not land on the roof? After all, it's safe from the fox & coyote also living in the neighborhood (as well as dogs, cats, & humans). I guess urban & suburban wildlife must find ways to adapt. Of course when I 1st told DH that we had a duck on the roof, he thought I was nuts. It's very common here to see our web-footed friends waddling on any roof that's not too steep, but it did take a little getting used to. As a kid, I only saw ducks/geese when fishing at the pond, and now we have them nesting out front - far away from any pond.
Since then, DH & I make a joke of it. Whenever we see a duck or goose on the roof, he pretends not to see it & says I'm crazy
