Santa Barbara, California, USA.
Differs very weakly genetically from P. hudsonia and very possibly merits reunification with that species and also with P. pica#R. Differs, however, from hudsonia in its yellow bill and variable yellow area around eye (3); somewhat different voice, with shorter upslurred whine-call (1) and slightly higher-pitched chatter-call (1)#R; smaller size (at least 1), although S populations of hudsonia “are, on average, smaller and smaller-billed than northern birds and tend to show a small patch of bare skin around the eye, thus approaching [nutalli] in appearance”#R; and more colonial habit (1). Lack of internal information in original description means spelling cannot be emended to nuttalli#R. Monotypic.
California W of Sierra Nevada Mts (Sacramento Valley, San Joaquin Valley, and valleys of S Coast Ranges), in SW USA.
