BREWSTER: BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 191 



Mr. Fraz;ir met witli the Long-tailed Chat only at San Jose del Cabo, where 

 eight specimens were taken at various dates between September 15 and Octo- 

 ber 25. Mr. Belding notes it as rare, without mentioning just when or 

 where he found it. Mr. Bryant says that it is common at Comondu "nesting 

 in the bushes of the creek." The Mexicans call it the " 'arriero' from the 

 resemblance of its whistle to that made by a mule driver." Mr. Anthony con- 

 siders it " common in the lower valleys " about San Pedro Martir, but it was 

 "only seen occasionally along the base of the mountain."^ In summer it 

 ranges as far north as Oregon, breeding rather freely throughout most of Cali- 

 fornia, and in winter it is not uncommon in western Mexico.

Mr. Belding gives this species as rare, but states that it was observed at 

 several places in the lowlands about La Paz and southward. Mr. Frazar took 

 only two specimens at La Paz, the first on February 5, the second on March 

 .21. On the Sierra de la Laguna he shot a female on May 4, and a male on 

 May 31. After this none were seen until August 25, when a specimen was 

 taken at San Jose del Cabo. Here the bird soon became common, its num- 

 bers increasing steadily up to the middle of October after which they dimin- 

 ished rapidly. This, with the fact that only one or two were seen at San Jos^ 

 del Rancho in December, led Mr. Frazar to conclude that the majority pa.ss to 

 the southward of the Cape before winter sets in. Mr. Bryant " found a few 

 at Comondu in March, before the migration northward had ended." Mr. An- 

 thony states that about the middle of May, 1893, " before we left the pine belt " 

 on San Pedro Martir, " this warbler had become common along the streams ; 

 more abundant, however, in the lower valleys during migrations." ^ Aside 

 from this statement there is no present evidence to indicate that the Pileolated 

 Warbler breeds anywhere on the Peninsula, but it is a rather common sum- 

 mer resident of most parts of California and northward, along or near the coast, 

 into Alaska. It migrates southward as far as Costa Rica and Panama.
