Sadly, the four little bats all perished. The first two, within an hour of intake (one actually in transit), and the other two, within twelve hours. They had been a whole day without nutrition and by the time we got them, they were very dehydrated and thin. Although they ate eagerly, it was just a little too late for these pups. I'm not sure what species they were, but I'm guessing they were in the myotis family, possibly "Big Brown" bats. I read that these bats have nursery colonies and the babies often end up on the ground, where they cry incessantly until their mothers come swoop by and pick them up. So, we learned something from these little ones. The experience they provided us will help future cases.
