1914 BIRDS OF ARIZONA . 69 



304. Dendroica coronata (Linnaeus). 



MYRTLE; WARBLER. 



Status Four records: One from the Chiricahua Mountains, March 26, 

 1881 (Brewster, 1882, p. 137) ; one from Tucson, January 28, 1886 (Scott, 1888, 

 p. 34) : Pima Indian Reservation, September, "one seen" (Breninger, iQoia, p. 

 46) ; Tucson, one seen January 28, 1912 (Sloanaker, 1913, p. 197). 



305. Dendroica auduboni auduboni (Townsend). 



AUDUBON WARBLER. 

 Synonym Sylvicola andubonii. 



Status Common summer visitant in high Transition and upward in the 

 mountains of northern Arizona : San Francisco Mountain, Mogollon Mountains, 

 etc. Abundant in winter in the Lower Sonoran valleys of the southern and west- 

 ern parts of the state: Tucson, San Pedro River, Yuma, etc. Winter visitant in 

 the Colorado Valley at least as far north as Fort Mohave. Occasional in winter 

 . at Fort Whipple (Coues, i866a, p. 69). Very abundant and of general distri- 

 bution during the migrations. 



306. Dendroica auduboni nigrifrons Brewster. 



BLACK-FRONTED WARBLER. 



Synonyms Dendroica auduboni, part : Dendroica nigrifrons. 



Status Reported from the Hnachuca and the Chiricahua mountains, where 

 it is a fairly common summer visitant in the Transition zone. D. o. auduboni has 

 been recorded as an uncommon summer visitant in the Santa Catalina Mountains 

 (Scott, 1888, p. 34). but I have seen typical examples of nigrifrons (in the col- 

 lection of F. S. Daggett) taken in these mountains in June, 1906, so that the breed- 

 ing range of this form extends at least that far north. Probably it includes all the 

 high mountains south of the Mogollon Plateau, but it is impossible at present to in- 

 dicate exactly the dividing line between the breeding ranges of nigrifrons and 

 andiiboni. From the critical comments made upon Dendroica andnboni by Coues 

 in his "List of Birds of Fort Whipple" (i866a, p. 69) it is evident that he collect- 

 ed in that region specimens approximating the characters of D. a. nigrifrons. 



307. Dendroica graciae Baird. 



GRACE WARBLER. 



Status A summer visitant in the Transition zone of eastern and central 

 Arizona, apparently least abundant in the extreme southern part of the state. Tn 

 the Huachuca Mountains it is common during the migrations, but decidedly rare 

 in the breeding season. Reported from the Huachuca, Chiricahua, Santa Catalina. 

 Mogollon, and White mountains. San Francisco Mountain and Fort Whipple. 

 There is no record of its occurrence in the lowlands during the migrations. 



308. Dendroica nigrescens (Townsend). 

 BLACK-THROATED GRAY WARBLER. 



Status A common summer visitant in low Transition throughout Arizona. 

 Has been found breeding in the Huachuca, Santa Rita. Whetstone, and Santa 

 Catalina mountains, San Francisco Mountain, and at Fort Whipple. Abundant 

 and generally distributed during the migrations.
