Mr. Bryant took specimens at Tia Juana on May 2 and observed others at 

 Hansen's on May 14. lie states tliat " Mr. Anthony has found it only in the 

 region of San Pedro Martir where it breeds from 7,500 to 11,000 feet altitude.' 



In California D. niffrescens occurs chiefly during migration, but it also breeds 

 sparingly in the Sierras from San Bernardino county northward through Ore- 

 gon and Washington into British Columbia. It is a common bird in western 

 Mexico in autumn, winter, and early spring, but it has not been found south 

 of the State of Oaxaca.

Mr. Belding's mention of a male seen at Miraflores, on April 4, 1882, is the 

 only record for the Cape Region, but the same observer, according to Mr. Bry- 

 ant, shot some specimens at Tia Juana on May 2, and " Mr. Anthony has talien 

 a single bird in spring at San Quintin " (Bryant) and another on May 7 at San 

 Fernando, while in 1893, in the region about San Pedro Martir, he saw a dozen 

 or more in the live oaks in Burro Caiion on April 23, and a number of others 

 at Yalladares, and " on the west side of San Pedro " on May 3 and 4.^ 



Townsend's Warbler occurs regularly, and at times commonly, in California, 

 at its seasons of migration, as well as occasionally in winter,^ but it is not 

 known to breed in this State, even among the higher mountains. Its summer 

 range extends from Oregon and British Columbia to Alaska, where it is toler- 

 ably common at Glacier in the Yukon valley.' During spring and autumn it 

 is apparently more numerously represented in the Rocky Mountains than near 

 the Pacific coast, and in Mexico its principal path of migration evidently lies 

 along the range of the Sierra Madres, for Mr. Frazar found it exceedingly abun- 

 dant in the early autumn of 1888 in the more elevated parts of the province of 

 Chihuahua. It is said to occur commonly in winter in Guatemala, south of 

 which it has not as yet been found.
