316 BIRDS OF WESTERN AND 



292. Erismatura dominica (Linn.). 

 Tepic, Grayson. 



" I found this duck, or several pairs, about fifty in all, that frequented a small lake or lagoon near the city 

 of Tepic in Jalisco, as late as the month of June. They were evidently desirous of breeding in that locality ; 

 the females shot by me showed enlarged ovaries. I have not met with this duck in the neighborhood of 

 Mazatlan."

" " Proc. Bost. Soc. of N. H., xiv, p. 302. 



Mazatlan, Bischoff ; Isabella Island, Grayson. 



" This species breeds upon the gi-ound near the sea beach, the nest containing usually two eggs, or young. 

 The voice of the female is harsh, while that of the male is a shrill whistle. I never saw the male feeding the 

 young, although he assists in incubation, and taking care of the young in the absence of the female. I found 

 them in great numbers breeding upon the Island of Isabella, and in the latter part of April the nests con- 

 tained nearly all young, or eggs ready to be hatched. One, and sometimes two, eggs in a nest, of a gi-eenish 

 white, and rough on the outside ; inside of shell pale green. The nests were on the lower surface of the 

 island, near the sea, many on the sea beach ; the young are fed by inserting the bill down the old one's throat."

 of a goose egg."
