MEXICAN GREBE. 
(Colymbus dominicus brachypterus.) 
The Mexican grebe, the smallest representative of its family found 
in North America, is fairly common in favorable localities in southern 
Texas, but is not known to occur elsewhere in the United States. 
In the lower Rio Grande Valley, near Brownsville, it is reported to 
nest in fair numbers and may be resident throughout the year. 
In general habits this bird is said to resemble other grebes. It 
is found in small ponds and lakes where there is proper concealment 
furnished by growths of cat-tails, rushes, and sedges. 
Philip Gosse* records that the stomachs of birds killed by him 
were filled with a finely ground substance which, from his descrip- 
tion, appears to have been feather remains, so that it would seem 
that the Mexican grebe shares the feather-eating habit of its relatives. 
No other references to the food of the Mexican grebe have been 
found in literature, and as there are no stomachs of this species at — 
hand for examination, no further data are available in regard to — 
its economic status. It is probable that the bird lives largely upon ~
