Birders,
Swinhoe's White-eye and Pin-tailed Whydah have now been accepted unanimously as established naturalized species by the CBRC, and both species are now placed on the CBRC's official California state list. These additions bring the California list to 695 species, of which 19 are established introductions.
Swinhoe's White-eye (*Zosterops simplex*) is placed on the California list in the family "Zosteropidae - White-eyes, Yuhinas, and Allies" following Wrentit. Pin-tailed Whydah (*Vidua macroura*) is placed on the California list in the family "Viduidae - Whydahs and Indigobirds" following Northern Wheatear.
Packages recommending acceptance of these two species were prepared by the CBRC's Introduced Birds Subcommittee following CBRC's policies and procedures about naturalized species. [See by-laws section VI-B-8 at https://www.californiabirds.org/CBRCbylaws.html ]
The CBRC does not attempt to determine which California counties have established populations of these (or other) non-native species; such determinations will be up to county compilers for NAB, county eBird reviewers, or others.
