Evidence of bat use under a highway bridge in western Montana
Bat guano accumulation beneath a highway bridge — evidence of night roost use

During May–October 2014, we surveyed 412 roadway bridges across Missoula, Ravalli, and Mineral Counties. Nearly half of all bridges (45.9%) showed evidence of bat use as night roosts between foraging flights. Day roosts, where bats shelter during daylight hours, were found at a smaller number of bridges (2.7%), ranging from solitary individuals to colonies of hundreds of females and their offspring. Bridge type and structure were significant predictors of bat use.

Field Notes

Whittle, E. (2019). “A Rare Observation of the Black Hills Redbelly Snake.” The Black Hills redbelly snake (Storeria occipitomaculata pahasapae) is a tiny, secretive subspecies with an extremely limited range — one of the least-known reptiles in the region. Encountering one during bat fieldwork was a memorable surprise. Read on my field blog


Media Appearances

PBS Nature: Wild Hope — “Bat Vax”

I am featured in “Bat Vax” (Episode 41), part of the Wild Hope series on PBS Nature. The episode follows our team into the field in Wyoming as we work to vaccinate northern long-eared bats against white-nose syndrome — a fungal disease that has killed millions of bats across North America. Led by USGS epidemiologist Dr. Tonie Rocke, we are among the first to attempt field vaccination of this endangered species. Watch on PBS


SciShow Talk Show

In November 2014, I joined Hank Green on SciShow Talk Show to discuss bat biology, echolocation, white-nose syndrome, and what it’s like to study bats in the field. We also met Carlos the Sinaloan Milk Snake from Animal Wonders. The episode has been viewed over 100,000 times on YouTube.
