Tlie Canvas-back was abundant in winter at the lakes and marshes of 

 the Great Basin, and it was also shot in May at Pyramid Lake, when other 

 species were breeding. In June, either this species or the Red-head was 

 very abundant in the tule-sloughs in the vicinity of Sacramento, where 

 they were undoubtedly breeding. We could obtain no specimens, however, 

 although numbers were seen, and are consequently doubtful as to the species.
