In my town in the summer, there’s a spot where just after sunset you can see the flocks of swallows retreating from the fields while flocks of bats arrive from the other side. It is cool to see.

Ratpenat in Catalan, winged rat.

In my language they are called “ratapinyada” or “ratpenat” from the latin for winged rat.

I don’t know about the insect population in my backyard but I do know that it is a safe haven for wall lizards, they don’t even hide anymore when I’m there.

Does that really work? I get the impression that people would go pee on that wall just to see it bounce.
