April 2023 Meeting

Western Bluebird Nest Box Program: A Tehachapi Citizen Scientist Project Since 2000
Presented by Karen Pestana

Karen Pestana will present Tehachapi Audubon’s on-going, 23-year Western Bluebird Nest Box program, including instructions on how to become a Citizen Science Nest Box Monitor and set up a nest box in your yard.

Her talk will included a 10-minute nest-cam video that captures western bluebirds in the nest box from laying eggs to young birds fledging. Secondly, she will give a presentation about western bluebirds and other local birds that use the nest boxes and how to join her group of volunteers as a nest box monitor.

Since 2000 Karen has coordinated volunteers to maintain and monitor 60+ Tehachapi bluebird nest boxes and report the findings to Cornell University Lab of Ornithology’s NestWatch program. She is a wildlife biologist formerly at Edwards Air Force Base and held positions with California Fish and Wildlife and the National Park Service.
