I don't recall how many minutes (degrees?) of arc the moon covers in
the sky (haven't run across it in this book), but it's a very small
piece of the whole. Seems to me that there must be an awful lot of
bats up there (and most of them very high, judging by their apparent
size in the scope for me to see that many in that short a time.

Anyone here know how to extract any useful information from this?

Probably a lot of bats following a really big lot of insects. You know
how they fly to lights? They didn't develop that after humanity
discovered artificial light. Some insects have probably always flown
at the moon (or in that general direction) as some part of their
instinctive drives. I'd guess mating drives. High flyers being
desired as the best of their gender by the opposite gender.

Whatever makes the insects go, will make the bats follow.

Or, there could be a cave or bat house or abandoned building nearby
enough that the live in so that when they fly from their day time
home, they go over / past your house and you generally don't know
they're there.
