PACIFIC COAST AVIFAUNA No. 10 



3- Vermivora celata lutescens (Ridgway). 



LUTESCENT WARBLER. 



Synonyms Hclminthophaga celata; Hclminthophila celata lutescens. 



Status An abundant migrant, occurring in all parts of Arizona. Has been 

 found at every point where collecting has been carried on in the spring and fall. 



3 or - Peucedramus olivaceus (Giraud). 



OLIVE WARBLER. 



Synonym Dendroica olivacea. 



Status Breeds in the Transition zone of the mountains of southern and 

 central Arizona. Has been found in the Huachuca, Chiricahua, Santa Catalina. 

 Mogollon and White mountains, and on Mount Graham, and there are other high 

 ranges at intermediate points where it will also probably be found. It does not 

 appear to be very abundant in any part of its range in Arizona. A few individ- 

 uals probably remain through the winter, as it has been reported from the Santa 

 Catalina Mountains, at 10,000 feet altitude, November 26-29 (Scott, i885b, p. 

 172), and from the Huachuca Mountains at 9000 feet, February 21 (Swarth, 

 I90 4 b, p. 53). 



302. Dendroica aestiva sonorana Brewster. 



SONORA YELLOW WARBLER. 



Synonyms Dendroica aestiva, part; Dendroica aestiva morcoiui, part. 



Status A common summer visitant in southern and western Arizona, ap- 

 parently confined almost entirely to the Lower Sonoran river valleys, the Colorado 

 and the Gila, with their tributaries. Has been reported from various points along 

 these streams : Fort Mohave, Yuma, Gila Bend, Tucson, Tombstone, etc. ; and 

 occasionally from localities in Upper Sonoran : Santa Cataiina Mountains, resi- 

 dent up to 4500 feet (Scott, 1888, p. 34) The northernmost record I have seen 

 from central Arizona is from Fort Verde (Coale, 1894, p. 218). I know of no 

 breeding record of a yellow warbler from any point in Arizona north of the 

 Mogollon Divide ; what form it is that migrates through this region I do not 

 know (Dendroica aestiva Merriam, 1890, p. 98, San Francisco Mountain, etc., 

 August and September; Fisher, 189313, p. 113, confluence of Beaverdam and Vir- 

 gin rivers, May; etc.). 



303. Dendroica aestiva brev/steri Grinnell. 



CALIFORNIA YELLOW WARBLER. 



Synonyms Dendroira aestiva, part; Dendroica aestiva morcomi, part. 



Status A common migrant in southern Arizona. I have seen specimens 

 from the Huachuca Mountains, in the extreme southeastern portion of the state 

 (Swarth, 1904^ p. 53), and from points on the Colorado River (Mus. Vert. 

 Zool.). These are distinctly D. a. brcivsteri, as distinguished from D. a. aestiva 

 of the eastern United States.
