How many baby Gray bats are in a litter?

A Gray bat (Myotis grisescens) usually gives birth to around 1 babies.With 1 litters per year, that sums up to a yearly offspring of 1 babies.

Upon birth, they weight 2 grams (0 lbs) and measure 2.9 cm (0′ 2″). They are a member of the Vespertilionidae family (genus: Myotis). An adult Gray bat grows up to a size of 4.4 cm (0′ 2″).

The gray bat (Myotis grisescens) is a species of microbat endemic to North America. The creature once flourished in caves all over the southeastern United States, but due to human disturbance, gray bat populations declined severely during the early and mid portion of the 20th century. At one cave alone, the Georgetown Cave in northwestern Alabama, populations declined from 150,000 gray bats to 10,000 by 1969. 95% of gray bats now only roost in 9 caves. M. grisescens has been listed as federally endangered by the U.S. Fish and Wildlife Service since 1976, and is protected under the Endangered Species Act. Gray bat populations were estimated at approximately 2 million bats around the time they were placed on the Endangered Species list. By the early 1980s populations of gray bats dropped to 1.6 million. With conservation efforts in place, in 2002, gray bat populations were estimated to have reached 2.3 million.
