ANATIN^ — THE DUCKS — ERISMATURA. 107 



According to the observations of Dr. Cooper, it is present in all parts of California 

 during the winter, both on fresh and on salt water. The young are very tame, and 

 may readily be approached ; but the adult l)ird is more shy, and full-plumaged speci- 

 mens are not easily procured. Dr. Cooper met with a number of these Ducks at 

 Santa Barbara, in a marshy pond, as late as the middle of May, and he thinks that 

 probably a few remain to breed within the limits of that State, though their chief 

 resort appears to be in regions farther north. This conjecture has since been verified, 

 as I have in my cabinet a set of the eggs of this bird taken by Mr. William A. Cooper 

 near Santa Cruz. 



Colonel Grayson mentions meeting with this species at Tepic, in Western Mexico, 

 and also at Mazatlan — where, however, it Avas rarely seen. Mr. Boardman speaks of 

 its occurrence in the vicinity of Calais as occasional, both in the spring and in the 

 fall ; but he does not think that it remains there to breed. 



It is frequently met with in Massachusetts, being much more common there in the 

 fall than in the spring, especially on ponds of fresh water ; and Mr. William Brewster 

 informs me that he has shot as many as thirteen of these Ducks in a single morning. 

 They arrive in quite large flocks of from thirty to forty, are very tame, and permit 

 a boat to be roAved close up to them ; and, as they rise very slowly from the water, 

 they may be very readily shot. 



Mr. Giraud found this species comparatively rare in the vicinity of New York ; it 

 is, however, quite common on Chesapeake Bay, Avhere it is known to hunters as the 

 Salt-water Teal. It is said to frequent the salt-ponds along the sea-coast, and to pro- 

 cure its food by diving, subsisting chiefly on marine plants. A writer in "■ Doughty's 

 Cabinet " calls this species the Heavy-tailed Duck, and states that it arrives on the 

 waters of the Upper Chesapeake Bay as early as the first or second week of October. 



Mr. Nelson speaks of it as being very common in ISTorthern Illinois during its 

 migrations ; it is a summer resident in that State, and occasionally breeds there. 

 The spring migrations begin about the middle of April and continue until the 5th of 

 May. A few of this species return early in October ; but the main migration takes 

 place a month later than that. Mr. T. H. Douglas, of Waukegan, is cited as having 

 met with a pair of these birds, with eight or ten young, in a small lake near that 

 place, and as saying that there is good reason to suppose the young had been hatched 

 in the vicinity. Mr. Kelson several times started females while incuba.ting : the nests, 

 however, he was never able to find. These occurrences took place about the middle 

 of June ; and the circumstances were such as to leave no doubt that the birds were 

 actually breeding in the neighborhood. 



Mr. J. A. Allen met with this Duck in September in the valley of Great Salt Lake, 

 where it Avas very common. It is also more or less abundant on the waters of most 

 of the interior rivers and ponds. 



Audvibon noticed it in large numbers during the Avinter months in Florida, some- 

 times shooting upAvards of forty in a single morning ; and he was informed by Dr. 

 Bachman that this species had been becoming more and more abundant in South 

 Carolina; yet he had never met with an example in full summer plumage. This 

 Duck seemed to be equally fond of salt, brackish, and fresh Avater. In the Southern 

 States it congregates in great flocks. Its flight is rapid, Avith a whirring sound, occa- 

 sioned by the concave form of the Avings. It rises from the Avater with considerable 

 difficulty, being obliged to assist itself with its broad webbed feet, and for that pur- 

 pose to run on the surface for several yards. From the ground, hoAvever, it can 

 spring up at once. This Duck swims Avith ease and grace and deeply immersed. It 

 is also extremely expert at diving ; and Avhen wounded, often escapes by doing this.
