Mr. Bryant took specimens at Tia Juana on May 2 and observed others at 
Hansen’s on May 14. He states that ‘* 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. nigrescens 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 taken 
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 Cafiion on April 23, and a number of others 
at Valladares, and “on the west side of San Pedro” on May 3 and 4.1 
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.
