BREWSTER: BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 215 
The Dwarf Thrush was found in January at Cape St. Lucas by Mr. Xantus, 
and Mr. Belding has reported it “common ; possibly resident ” in the “ Victoria 
Mountains.” It is probable, however, that some of the birds seen by the 
latter observer were H. g. audubont, which is not uncommon, and doubtless 
breeds in these mountains, and that the Dwarf Thrush occurs in the Cape 
Region only during the migrations and in winter, and then in no great 
numbers. This, at least, is Mr. Frazar’s opinion, and it is confirmed, in 
the main, by the evidence afforded by his skins, although it must be ad- 
mitted that it is difficult to account for the excessively worn and generally 
shabby condition of plumage of the specimen above referred to, other than by 
the assumption that it was a breeding bird. If audubont and guttata really 
pass the summer together or in close proximity in the Cape Region without 
interbreeding, the case will be one of peculiar interest in view of the fact that 
both are regarded as mere geographical forms of the same species. 
Mr. Bryant states that he “saw a few” “ Dwarf Thrushes” on Santa Mar- 
garita Island in January, 1888. They do not appear to have been met with 
anywhere in the central or northern portions of the Peninsula, either by him 
or by Mr. Anthony. 
Merula migratoria propinqua (Rivew). 
WESTERN RoBIn. 
The relationship of a Robin taken by Mr. Frazar at San José del Rancho 
on December 22, 1887, is open to some doubt, for the specimen is apparently 
intermediate between migratoria and propingua, combining the large, distinct, 
white tail spots of the former with the decidedly ashy back, and restricted 
black on the head, of the latter. On the whole, however, the bird seems to 
be nearest propingua, a form which has not been previously reported from 
the southern portion of Lower California, although in the northern districts 
it is not uncommon in winter and early spring, feeding chiefly on manzanita 
berries and ranging at least as far southward as San Quintin. 
The Western Robin is a winter visitor only, to the lowlands of California, 
but it breeds in the mountains as far south as Los Angeles county and north- 
ward into British Columbia. In Alaska it is unknown, all the Robins of that 
region being, apparently, true megratorza. Salvin and Godman state? that 
the latter occurs in summer in the mountains of Orizaba, and that they have 
examined a young bird in spotted plumage taken near the City of Mexico, 
while they make no mention of M. m. propinqua, but all my winter specimens 
from western Mexico, as well as several breeding birds shot at Pinos Altos and 
Jesus Maria, are typical propinqua.
