BREWSTER: BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 47: 
of my specimens from the eastern or central portions of North America. In 
all other respects they seem to agree perfectly with eastern birds of the same 
age and sex. 
The Ruddy Duck appears to be resident in the Cape Region. It was found 
by Mr. Xantus at San José del Cabo in December and February, and at Laguna 
de Santiago, and in the Saint Lazaro Mountains in January. According to Mr. 
Belding it was “ very common” in the “ vicinity of La Paz, and southward ”’ 
in the winter and early spring of 1882-83. 
Mr. Frazar met with it first at San José del Cabo, where two were seen on 
October 18 and a few during the following week. At the time he naturally 
supposed these birds to be migrants from further north, as indeed they may have 
been, but on reaching Santiago early in November he found, in the lagoon al- 
ready mentioned (in connection with the Short-winged Grebe), a large breeding 
colony of Ruddy Ducks, most of which were young of various sizes still following 
their mothers. Two specimens in his collection taken, on November 16, from a 
brood of five, cannot have been more than a few days from the egg when killed. 
The late date at which these young birds were found is somewhat difficult to 
explain, for in Mexico and Central America, where the species is said to breed 
numerously, the eggs are laid in May or June. Mr, Frazar was told, how- 
ever, that the lagoon at Santiago, which, at the time of his visit, was filled 
with water several feet in depth, dries up every few years, and this fact may 
have something to do with the unusual season at which the Ruddy Ducks and 
Short-winged Grebes were breeding there. The Ruddy Duck has been “ found 
nesting at lat. 31° N. by Mr. Anthony ” (Bryant), and Mr. Grinnell states that 
it breeds sparingly in Los Angeles county, California.?

AMERICAN WHITE-FRONTED Goose. 
Anser albifrons gambeli Bryant, Proc. Calif. Acad. Sci., 2d ser., IT. 1889, 267 (Los 
Martires). 
The American White-fronted Goose is not mentioned in any of the earlier 
papers relating to the Cape Region, but Mr. Belding told Mr. Bryant “that a 
hunter (Mr. Fisher) shot one of a group of four at Los Martires, between La - 
Paz and San José del Cabo ” (Bryant). 
“ Mr. Grayson met with this species on the western coast of Mexico, near 
Mazatlan, where, from the month of September until February, it occurs in 
considerable flocks, appearing to migrate up and down the southern Gulf 
shores.” 8 It is also abundant in winter in California. Its breeding grounds 
lie far to the northward of the United States.
