The California Bird Records Committee has accepted records of two species new to the California state list:
Band-rumped Storm-Petrel (Oceanodroma castro) at SE Farallon Island, San Francisco Co., 10-11 Nov 2017 (2017-130); and
Citrine Wagtail (Motacilla citreola) at Yolo Bypass, Yolo Co., 15-16 Dec 2017 (2017-160)
Note that each of these species comes with taxonomic uncertainties. “Band-rumped Storm-Petrel” may represent a complex of several species; there are perhaps four distinct populations within the Pacific Ocean alone, and each of these differs from the up-to-five distinct taxa in the Atlantic Ocean (see Petrels, Albatrosses and Storm-Petrels of North America by S. N. G. Howell, Princeton Univ. Press, 2012). Citrine Wagtail and Eastern/Western Yellow Wagtails form another confusing complex (see Pipits and Wagtails by P. Alstrom and K. Mild, Princeton Univ. Press, 2003); mtDNA work had suggested that the two clades of Citrine Wagtail were each more closely related to different Yellow Wagtail clades than to each other, but nuclear DNA work appears to confirm the distinctness, and monophyly, of Citrine Wagtail.
Another potential state first, a Hawfinch (Coccothraustes coccothraustes) aboard a ship offshore of San Luis Obispo and Santa Barbara Counties, 17 May 2016 (2016-150), was not accepted due to questionable natural occurrence.
The addition of the storm-petrel and wagtail brings the California state list to 671 species. Thanks to Joe Morlan, the CBRC web site has already been updated with this
