8 PACIFIC COAST AVIFAUNA No. 11 
printed synonyms are entered in the Index, so that the latter may be used as a 
means of identifying any name in the literature of California ornithology. 
The terms employed for comparative abundance are the usual simple and 
relative ones: Abundant, common, fairly common, rare. Seasonal status is in- 
dicated by these terms: Resident, meaning permanently present throughout the 
year; summer visitant, indicating presence only during the summer season which 
is also-usually the breeding season; winter visitant, of obvious meaning, comple- 
mentary to summer visitant; transient, passing through during spring and fall 
migrations and tarrying neither for the summer nor the winter. Occasional 
qualifying words are used, with the intention always of leaving the meaning 
clear. ; 
This is solely a distributional paper; it has nothing to do with migration, 
extent of breeding season, or systematic status, exeept in the latter case in so far 
as is necessary to elucidate distribution. The distributional terms employed are 
explained on succeeding pages (pp. 9-12). The maps (pls. I-III) should be con- 
tinually consulted. In using this list it must be kept in mind that only with the 
rarer species are all records of occurrence cited. With by far the greater num- 
ber of species, only the first or most important for each critical locality is given; 
also only such localities are specifically noted as represent extremes of range, 
like northernmost, easternmost, ete., or are otherwise specially worthy of atten- 
tion, 
Citations to articles are, of course, given in uniformly abbreviated form. 
Where the title of the periodical or book is not clearly apparent, reference should 
be made to my Bibliography of California Ornithology (Pacific Coast Avifauna 
number 5, 1909). Where more than one person of the same surname has contrib- 
uted to Californian ornithology, the appropriate initials are used in citation; for 
example, J. G. Cooper, W. A. Cooper. But otherwise the surname alone has 
seemed sufficient ; as: Gambel, Heermann, Torrey. 
An effort has been made to give the location, in museums or private collec- 
tions, of specimens which form the basis of extraordinary records, as in the ease 
of species which have been reported from the state less than four times. |
