102 LAMELLIROSTRAL SWIMMERS — ANSERES. 



season. A large number of examples ot this species were taken near the Calumet 

 Marshes during the fall of 1875, and many others Avere seen, arriving the last of 

 October and departing toward the end of March. A single specimen of this bird, 

 in immature plumage, was procured on the Wabash by Professor Stein, in October, 



1875. 



It is said to be abundant on the Pacific coast near San Pedro ; but it was not 

 found inland, nor on any of the interior lagoons, apparently never leaving the sea and 

 its estuaries. Dr. Cooper also writes that this is an abundant species in the win- 

 ter along the entire Pacitic coast, associating with the other Surf Dvicks, and having 

 habits similar to theirs. Being but little hunted, and having but few enemies among 

 the wild animals, many of this species become very old, and linger along the southern 

 coast in large flocks — some of them finally dying of old age. The long rainy sea- 

 sons are frequently fatal to them, as at that time they seem to be very delicate, and 

 are peculiarly subject to the influences of the weather. Many become very thin, and 

 even blind, at the time of assuming their spring plumage, and swim, unconscious 

 of danger, near the wharves and shores, or after storms are found dead along the 



beaches. 



Audubon states that in his visit to Labrador, in the spring of 1833, he found this 

 species not the least numerous of the various kinds of Ducks with which the waters 

 of that region seemed to be alive. The numbers of this species that passed the 

 shores of Labrador bound for the far north exceeded all his previous conceptions. 

 He noticed that a few pairs had remained in the neighborhood of Little Macatina, 

 and on examining a fresh-water marsh he suddenly started a female Surf Duck from 

 her nest. This was snugly placed among the tall leaves of a bunch of grass, and 

 raised a few inches above the roots. It was entirely made of withered and rotten 

 weeds, the former being circularly arranged over the latter, producing a well-rounded 

 cavity 6.00 inches in diameter, and 2.50 deep. The borders of the inner cup Avere 

 lined with the down of the bird, and in it there were five eggs. These were 2.31 

 inches in length, by 1.G3 in breadth, and about equally rounded at both ends. The 

 shell was perfectly smooth, and of a pale yellowish or cream color. 



Audubon states that Dr. Bachman met with this Duck in the winter as far south 

 as Charleston, S. C. He speaks of it as being a powerful swimmer and an expert 

 diver, but as rising from the water with some difficulty, and, when once under way, 

 flying with great rapidity. The female, as she rises from her nest, utters a rough 

 guttural cry ; but this Duck is generally a very silent bird. Audubon was assured 

 that in Newfoundland this species breeds in considerable numbers in the lakes and 

 ponds of the interior. Its stomach was found to contain fish of different kinds, 

 several species of shellfish, and quantities of coarse gravel. 



Mr. Lockhart observed this species breeding near the Arctic Sea. The nest was 

 on the edge of a small portage between two lakes, and concealed under the spread- 

 ing liranches of a stunted pine-tree. 



.Mr. MacFarlane found the Surf Duck breeding in considerable numbers in the 

 neighborhood of Fort Anderson and on the Lower Anderson Kiver, and a nest con- 

 taining six eggs was obtained July 5 on the margin of a small lake. It was not dis- 

 tinguisluible from the nests of the Velvet Duck. Another nest, containing eight eggs, 

 was found, June 25, on a ridge of ground at the foot of a dry stunted pine, and was 

 made of dark-colored down, being entirely concealed from view by the lower branches 

 of the pine-tree. This species of Duck was very numerous in the wooded country, 

 but the nests were found only with great difficulty. It was afterward ascertained to 

 be very abundant on the sea-coast about Franklin's Bay. All the nests found appear
