How much do we know about the native Foothill Yellow-legged Frog? Living in open, sunny and shady areas of the Sierra Nevada rivers and streams, they are cleverly camouflaged as they sit on river rocks sometimes broadcasting low pitched calls in the air and underwater.On this show podcast listeners will hear from Kevin Wiseman, an expert who has studied this particular frog for over 20 years. As a biologist and scientific illustrator with the Department of Herpetology at the California Academy of Sciences, Kevin leads the popular workshop Reptiles and Amphibians of the Sierra Nevada.In this episode, Critter Chat hosts and producers Susan Brandt and Marney Blair join Kevin on a field trip to the North Fork of the Yuba River to look for the Foothill Yellow-legged Frogs, their egg masses, and to learn about their behavior and migration patterns. Kevin’s current research is focused on several long-term ecological studies which includes the Foothill Yellow-legged Frogs, collecting and looking at data to understand the patterns these frogs go through year to year and to understand the cause of their population growth or decline. School teachers are encouraged to use Critter Chat for their students with teaching notes that include vocabulary words and concepts like a “lek” and “bi-phasic lifestyle.”Critter Chat is written and produced by Marney Blair and Susan Brandt and edited with KVMR news director Claudio Mendonca. Each episode features one species of the many critters that live in the Sierra Nevada foothills and mountains. Critter Chat was awarded the 2024 Jody Fenimore Excellence in Public Affairs and Community Service Programming by KVMR.Thanks to Courtney Silver-Peavey, PhD.
