An Exciting Catch- the Hoary Bat!

As mentioned in the previous weeks, there was one special bat that made its way into the top of our net during the 2022 bat field season that left us overjoyed! One juvenile, female hoary bat (Aeorestes cinereus) was captured during our last week of surveying. This is only the second time this bat has been captured at this site in the Pinelands. Even though the hoary bat is not an endangered species, this is a rare capture for our team because the species is generally flies high and our nets only go as high as 5.5 meters. Additionally, the habitat we survey is more suited to the Northern long-eared bat which like densely cluttered forests, whereas the hoary bat typically is found on the edges of open fields.

Summer Survey Yields 79 Bats

Bands, like the one in this photo, help us to determine how fidelic bats are to their foraging and breeding areas.

During the past two months, CWF biologists have spent many late nights surveying for bats in the Pinelands! A typical survey night starts just before sundown with setting up expansive nets across corridors in the woods. In the dark, these fine threaded nets are nearly invisible to bats and the occasional flying squirrel or whip-poor-will. As the sun sets, the bats emerge, rushing through the sky to their foraging grounds. Every ten minutes, from sunset till 2am, the nets are checked, and any captured bats are safely extracted to then be identified, weighed, and measured.

               Over the course of ten nights during the 2022 summer mist netting surveys, 79 bats were captured! That’s 30 more bats than were captured in 2021 in the same area of the Pinelands! Unfortunately, none of our target species like Northern long-eared bat or little brown bat were captured. Even though our survey goals were not met, there was still some exciting news throughout the season like recaptured bats from previous survey years. One recaptured bat was banded in 2018 which provides some insight into how site fidelic these bats can be to their foraging and breeding areas!
