Bears. Well, just because bears. It was an option, it speaks for itself.
In truth, spiders. Yeah, they're insects, but still, spiders only ever show up when it gets hot enough around here, and that's a surefire way of knowing spring/summer is about to dropkick you in the face.
Out of that list, birds would be the serious option. Specifically, seagulls. As terrible as it sounds. There are no bunnies around here, and deer and squirrels and shit flock to the village plaza during the winter. The other animals just sort of appear here and there on farms and such.
