A more appropriate name for a bat nursery is a maternity roost.
Most bat species give live birth to only one pup per year. However, some species can give birth to twins or multiple pups. For 3 to 4 weeks, the baby is incapable of flying and is latched onto its mother’s nipple. It is not until they are about five weeks old that the baby bat can begin flying lessons and leaves its roost.
When I still lived with my parents, their attic was a nursery for local bats. I could hear the baby bats and it was great. Then my parents had Orkin come out and seal off the attic when the mama and baby bats weren’t there. I hope the bats found another nursery nearby.
I hope so too!
