Point Blue Conservation Science, founded as the Point Reyes Bird Observatory (PRBO), is a California-based wildlife conservation and research non-profit organization. PRBO was founded in 1965 to study the birds migrating along the Pacific flyway, and has the longest running population study of landbirds in North America west of the Mississippi river (continuous since 1966) located in Marin County, north of San Francisco, as well as maintaining a year-round research presence on the Farallon Islands since 1969. PRBO, namesake of the Point Reyes peninsula which is protected as the Point Reyes National Seashore, is headquartered in Petaluma, California with several active field research stations and sites throughout California. Their field station in Bolinas, Ca offers environmental education, guided tours of the mist-netting process used to study birds, and seasonal interns are there all year learning about banding/studying birds. In June 2013, the organization changed its name to Point Blue Conservation Science.
