The American Eared Grebe is a common winter resident in the Gulf of Cali- 
fornia off La Pazas well as about the islands to the northward, where, during 
February and March, Mr. Frazar saw it frequently, often in large flocks and 
occasionally where the water was very deep. At San José del Cabo he met 
with it only once, on October 18, when a single bird was noted. Mr. Belding 
also mentions seeing it near La Paz. Mr. Bryant found it “common along the 
shores of Magdalena Bay, particularly at Magdalena Island. They were seen 
about the landing swimming in compact groups of from one to two dozen birds, 
the entire flock would dive almost simultaneously and appear again in a more 
scattered bunch a short distance away. Their tameness made them objects to 
be stoned by Mexican boys who occasionally killed and wounded some.” 
There is no evidence that the Eared Grebe breeds in any part of Lower Cali- 
fornia, although the southern limits of its known summer range lie not far to 
the northward, for it has been found nesting in California at Elizabeth Lake, 
Los Angeles county, and abundantly at Bear Valley Lake in the San Bernar- 
dino Mountains. In winter it migrates as far south as Guatemala. 
Colymbus dominicus brachypterus CHapmay. 
SHORT-WINGED GREBE. 
Tachybaptes dominicus (not Colymbus dominicus LINNAEUS) BELDING, Proc. U.S 
Nat. Mus., VI. 1883, 351 (San José, Miraflores, and Santiago). 
Colymbus dominicus (not of LinnaEus) Bryant, Proc. Calif. Acad. Sci., 2d ser., IL 
1889, 250 (San José, Miraflores, and Santiago). 
Of the thirty-one specimens of this Grebe collected by Mr. Frazar at Santiago 
about one-half are adults, the remaining half being young of various ages from 
chicks still in their natal down to fully grown birds in fresh winter plumage. 
On comparing these skins with eight West Indian examples of dominicus (two 
from Jamaica, three from the Bahamas, and three from Cuba), I find that the
