DRYOBATES VILLOSUS HYLOSCOPUS Cabanis and Heine. 



Dryobates hyloscopus Cabanis and Heine, Mus. Hem., vol. 4, pt. 2, 1S63, p. 69 

 (note). 



Chars, subsp. — Like Dryobates villosus orius, but decidedly smaller. 



Measurements.- — Male: 2 Wing, 118.5-125.5 (average, 121.7) mm.; 

 tail, 70-76.5 (73.2); exposed culmen, 28.5-32.5 (30.6); tarsus, 21-22 

 (21 6); middle toe, 13-14.5 (13.8). 



Female: 3 Wing, 114.5-122 (117.8); tail, 67-77 (73.7); exposed 

 culmen, 26.5-28 (27.2); tarsus, 19.5-21 (20.4); middle toe, 12.5-13.5 

 (13). 



Type-locality. — San Jose, California. 



Geographical distribution. — Canadian and Transition zones in the 

 mountains of southern California and northern Lower California: 

 south to the San Pedro Martir Mountains, northern Lower California; 

 east to the Cuyamaca Mountains and the San Bernardino Mountains, 

 central southern California; and the Grapevine Mountains, middle 

 eastern California; north, in the Sierra Nevada, to the White Moun- 

 tains; eaid through the coast ranges to Cahto and to Snow Mountain 

 (Colusa County), in northwestern California. 



The subspecies Dryobates villosus hyloscopus, as here restricted, 

 differs from Dryobates villosus harrisi in decidedly smaller size, and 

 very much less deeply smoky brownish lower parts and other light 

 areas. 



Unfortunately the type of D. v. hyloscopus came from San Jose, 

 California, in an area intermediate between the very small birds 

 of northern Lower California and the large representatives of Dryo- 

 bates villosus orius from northeastern California. In such a case 

 it seems proper to consider, as we do here, the extreme development 

 of the race as really typical, to which the type, like other interme- 

 diate specimens, is referable. Examples from southern and central 

 western California (San Diego County to Cahto) are, like the type, 

 somewhat larger than those from northern Lower California (length 

 of wing in the male averaging about 123.5 mm.), and verge toward 

 Dryobates villosus orius. Birds from the Piute Mountains, southern 

 California, are white below, and incline somewhat toward the Arizona 

 Dryobates villosus leucothorectis.
