Did you know that during the summer you can find up to 9 different species of bats in New Jersey?! Of those 9 species, 6 species can be found in New Jersey year round and the other 3 migrate to sub-tropical and tropical regions in the winter. While there are so many different types of bats the 2 species of bats that humans most often come in contact with are the big brown bat and the little brown bat.
Big brown bats have a large wingspan averaging 14 inches. This is the most common species of bat in New Jersey. Up to 200 individual bats can make up a colony and that colony will nest in the same place year after year if undisturbed. These bats are long lived, known to have lived for 20 of more years, they only birth 1-2 young per year. When looking at the number of bat contact with people every year, the big brown bat accounts for over 75% of the contacts. Because of this they are also the bat most often tested for rabies.
The little brown bats have a wing span of 8 to 11 inches. While they are known to hibernate in buildings such as homes in smaller numbers, they will also hibernate in large numbers in abandoned iron mines where hundreds to thousands can be found roosting together. The amount of exposures to humans and animals are less with the little brown bat, hence leading to smaller numbers of them being found rabid, or to have rabies. Populations of the little brown bat are quickly declining due to White Nose Syndrome, a fungal disease that affects hibernating bats. Because of this, the little brown bat along with the rest of New Jerseys bats are protected under the NJ Endangered and Nongame Species Conversation Act, making it illegal to hunt, capture or kill them.
