ground-dwelling insects. Pallid bats often emit a musky odor
when disturbed, a good protection from predators- think skunk.

OCTOBER - THE MONTH FOR OWLS AND BATS!
An interesting evening weather-wise and detection-wise. We started the night under clouds and warmth had one NSWO and one Pallid Bat (Antrozous pallidus) capture on our first net check. And bats are so cool! The Pallid bat flies low to eat insects on the ground, which is why we frequently catch them in our nets, but only at the beginning of the season. Pallids use their big ears to detect prey and often turn their sonar off. That is why they sometime don't detect the net, but once they know the nets are there, they turn on the sonar to avoid capture.
It was quiet and still after that, until the clouds parted, stars and cooler temps appeared and then came the owls. Saw-whets, screech and great horned began to call and we banded three more owls near the end of our night. Weather likely made a difference. Thanks Sheila Frisk, Julie Newman, Wyatt Hersey and Steve King!
