Field crew prepares to measure and tag a bat

A team of biologists prepares to measure, weigh, and tag a captured bats. On the left, USGS biologist Gabe Reyes has a bat in a bag, used to separate and calm the bats. USGS biologist Julia Ersan is holding some alcohol used to ensure clean instruments and work surfaces, and USGS biologist Austin Waag is getting something out of a backpack. NPS Biologist Michael Hansen is holding a box of radio tags on the right, and she has selected one to use. The scale and calipers for measuring the bat are on the rock in the middle, as are the scissors used to clip fur for the tag attachment.
