      I live in an HOA (obligatory Fuck them)

      They put up numerous bat boxes on poles around the common wooded area and a large retention pond right about the time Covid started.

      Main reason is it’s free insect killers. We have tons of pests anyway being so close to a wooded area and a lake + the retention pond we have and the added bats help to clear some of them out.

      As for the noise, no you really don’t hear them here. All the frogs are the loudest things heard of a night.

        Sitting out on my deck listening to the frogs/nature at night. I still hear the bats when they are within 20ft. It isn’t loud but you hear them. They are a pleasant addition to the symphony that goes on at night.

        Now… fuck pheasants at night they are loud and when you don’t know what the sound is its creepy

      Some species of bats spend more time in the upper ranges that no human can hear than others.

      The spotted bat for instance, is found on west coast if North America and mostly calls at 11khz well within even older human hearing while other bats operate entirely outside human hearing.
