534 - BIRDS—ANATID A. 
Buffle-head, or, as more frequently called, the Dipper Duck or Butter-ball, 
is more abundant on the streams than in ponds. No species is better 
known to the amateur sportsman than this, which frequently prefers to 
avoid danger by diving rather than by flight. They are usually seen 
in small flocks of from six to ten, among which the males frequently 
outnumber the females. Both sexes, however, are often seen singly or 
in company with other species. | 
Dr. Coues (Birds N. W., 575) describes the nest of this duck as placed 
in the hollow of a dead tree, and composed of feathers. The eggs are 
described as varying from buff to a creamy-white or grayish-olive color, 
and measuring from 1.67 to 2 in length by from 1.25 to 1.50 in breadth. 
GENUS HARELDA. Leach. 
Bill without lateral and superior extension of feathers and consequently without su- 
perior and lateral basal processes; the lateral outline of feathers oblique. Bill not

linear, in the posterior half of bill. Tail feathers long and pointed, in the male equal

Tail of fourteen narrow, pointed feathers, in the male in summer the central ones very 
slender and much elongated, nearly or quite equalling the wing ; nail of bill occupying 
the whole tip; seasonal changesremarkable. Malein summer with the back and the long 
narrowly lanceclate scapulars varied with reddish-brown, wanting in winter, when this 
color is exchanged for pearly-gray or white; general color blackish or very dark brown, 
below from the breast abruptly white ; no white on the wing; sides of head plaumbeous- 
gray; in winter the head, neck and body anteriorly, white, but the gray cheek-patch 
persistent, and a large dark patch below this; bill at all seasons black, broadly orange- 
barred. Female without lengthened scapulars or tail feathers, the bill dusky greenish, 
and otherwise different; but recognized by presence of head- and neck-patches, and 
absence of white on the wing. Length, 15-20 or more, according to tail; wing, 8-9. 
Habitat, Northern Hemisphere. Chiefly maritime. Also on the Great Lakes. | 
Not common winter visitor on Lake Hrie, and rare in the interior of 
the State. Mr. Winslow informed me in 1861, that the Long-tailed 
Duck was of not unfrequent occurrence on the lake, and I have since 
seen several specimens from Sandusky Bay. 
My friend, Dr. T. C. Hoover captured a fine male ina small creek near 
Bellaire, Ohio, February 9, 1877, and Chas. J. Orton secured a female in
