The park near my work, where I walk on my breaks, is unusally active with birds today, mostly robins but also a few sparrows and jays. They’re hopping on the ground and swooping from branch to branch all over the place, more so than usual. Not sure why. Doesn’t look like they’re gathering nesting material or hunting for bugs or anything practical like that, at least not that I can see. Maybe just goofing off and enjoying the nice day.
