BREWSTER : BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 165 



with excepting at San Jos^ del Cabo, where a few, evidently migrating, were seen 

 passing southward in late August and early September. 



Mr. Bryant records the Western Martin from several places iu tlie northern 

 portions of Lower California, and says that it has been found nesting by Mr. 

 Beldinf^ in dead pines at Hansen's. Mr. Anthony states that in the neighbor- 

 hood of San Fernando, it is " not uncommon at tlie mission and an occasional 

 pair was seen in other localities, nesting in Woodpecker holes in the giant cac- 

 tus," ^ while on San Pedro Martir it is " very common; nesting in colonies from 

 Valladares, 2,500 feet altitude, throughout the pines." ^ Mr. Frazar's experi- 

 ence indicates, of course, that the bird also breeds in the Cape Region, but he 

 obtained no direct proof of this. 



The Western Martin occurs in summer throughout most of California, and 

 probably still further northward. Its winter haunts are not definitely known.

Two Cliff Swallows taken by Mr. Frazar, both young birds with white-spotted 

 throats, are very much paler than any of my eastern examj^les in corresponding 

 plumage. In both, the rump is dull ochraceous buff, the forehead, nuchal coHar, 

 breast, and sides, pale drab gray with a slight tinge of rufous. The only decided 

 rufous is on the throat and sides of the head. These specimens are almost per- 

 fectly matched by a bird (No. 30,556) in the United States National Museum, 

 labeled as taken "at sea off the west coast of Central America, Oct. 20, 

 1863." It is not improbable that all three belong to a form as yet undescribed, 

 or possiljly they may be the young of some of the known Mexican and Central 

 American species of which I have seen only the adults. 



Mr. Belding mentions seeing the Cliff Swallow on April 29, 1882, at San 

 Jose del Cabo, where Mr. Frazar found it very ntimerous between September 

 8 and October 7, 1887. It occurred in lar^je, stragG^ling flocks which usually 

 contained varying percentages of other species of Swallows, most of which were 

 either migrating or collecting at this point preparatory to setting out across the 

 sea. Neither of the observers just mentioned met with the Cliff Swallow at 

 any other locality in the Cape Region. To the northward, however, it has 

 been found at San Quintin Bay in May by Mr. Belding (fide Bryant) and at 

 San Fernando ^ and San Pedro Martir by Mr. Anthony. At the locality last 

 named it was " common in colonies from the coast to the top of the mountain;
