Cavendar Pond Bat Presence Monitoring
Increasing our understanding of a cryptic and important local animal
With bat populations declining in many areas, the NFJDWC has partnered with the National Fish and Wildlife Foundation to monitor and better our understanding of these cryptic and often misunderstood animals. Using acoustic song meters deployed by our youth crews in the Cavendar Pond area, we are gathering data on the diversity and abundance of bat species here in the John Day Basin.
Local Bat Focus: Mexican(or Brazilian) Free-tailed Bat
The Mexican Free-Tailed Bat has been recorded in our own backyard, with recordings captured from a site on the Middle Fork John Day River. It is considered to be one of the most abundant mammals in North America, with a range from Oregon to Florida. Although there are large numbers of them, the Mexican Free-tailed Bat is considered to be of special concern due to roosting in large groups in select locations. These large groups can consume up to 250 tons of insects in one night! Fortunately, these bats are not as prone to White Nose Syndrome, a fungus that is infecting alarming amounts of bats, due to their preference for roosting in caves that are more arid.
