prising that it should follow the trends of these ranges into the United 

 States, as some other species have done. Early reports of the occur- 

 rence of the red-faced warbler in Texas having been discredited as 

 probably erroneous, it was definitely added to our fauna by Henry 

 W. Henshaw (1875), who "met \nt\\ the species at two points, near 

 Camp Apache, and again on Mount Graham, a point some two hundred 

 miles to the south. At the former place, several specimens were cap- 

 tured, including the young in nesting plumage, thus indicating that 

 they breed in the vicinity." 



The northern red-faced warbler is essentially a bird of the moun- 

 tain canyons, breeding quite commonly from 7,000 feet vipward in 

 probably all of the mountain ranges of southeastern Arizona and 

 southwestern New Mexico. Dr. Edgar A. Mearns (1890) found it 

 to be "a summer resident from near the lower border of the pine belt 

 to the summit of the Mogollon Mountains. It was not seen in the 

 San Francisco Mountains, but was found breeding about thirty miles 

 south of them," in Arizona. We found it common in Eamsay Canyon 

 in the Huachuca Mountains, mainly between 6,000 and 8,000 feet, 

 where the sloping sides of the canyon were clothed with spruces, firs, 

 and, higher up, with pines. Here the bright red faces of the otherwise 

 sombre-colored males flashed like glowing embers in the dark shadows 

 of the conifers and quickly caught the eye. 



Dr. George M. Sutton (1943) found it common in the Santa Rita 

 Mountains, south of Tucson, where "every open aspen copse visited 

 by the writer sheltered a pair of these handsome birds." Mrs. Bailey 

 (1928) mentions a number of localities in New Mexico where it has 

 been observed or found breeding. 



Spring. — The red-faced warbler may eventually be found breeding 

 farther north than is now known, as it seems to be more abundant in 

 southern Arizona on the spring migration than during the breeding 

 season, suggesting that some may be passing through that region. 

 O. W. Howard (1899) says: "These birds are quite common in the 

 mountains of Southern Arizona, especially during the spring migra- 

 tion. I have seen as many as four or five feeding in one tree. They 

 become scarcer as the season advances and at the time of breeding com- 

 paratively few of them remain." And Harry S. Swarth (1904) says 

 that, in the Huachucas, it is "found during the breeding season from 

 7000 feet ujd wards, and in the migrations as abundant in the higher pine 

 regions as anywhere. The fii-st arrival was noted April 20th, and up 

 to the middle of May they were seen in considerable numbers along 

 the canyons, often in company with other migrating warblers. Dur- 

 ing the breeding season their numbers seem to be greatly decreased, 

 but this is probably more apparent than real, as at this time they 

 are very quiet and inconspicuous; and as soon as the young begin
