Desert Oasis

This year I decided to expand the acoustic monitoring that I’ve been conducting at the River Fork Ranch in northern Nevada.  The Nature Conservancy has been supported of my efforts by graciously providing access to preserves, so I decided to try to monitor at other TNC preserves.  In April of this year, I headed south […]

Squirrel Chatter

On my recent trip through the Great Basin, I spent a night in a lovely place called Bowers Flat, near the resort town of Duck Creek, Utah.  This grassy meadow surrounded by Ponderosa Pines should actually have been called squirrel meadow, as within a few minutes of arriving, I heard the calls of yellow-bellied marmots,
