Delve into the world of avian conservation and citizen science! This upcoming meeting promises an enriching experience for bird enthusiasts and nature lovers alike.

In addition to discussing the nesting behaviors of Western Bluebirds, Karen will shed light on other local bird species that utilize the nest boxes, highlighting the interconnectedness of Tehachapi’s avian community.
