and small fish, wliieh it obtains by diving. In rivers and 

 lakes it feeds principally on the larvae and pupge of insects, 

 for which also it dives in clear deep water. The call-note 

 is an unmelodious quack or croak. 



The Golden Eye breeds only in high latitudes, and 

 builds its nest in holes of trees, often at the height of 

 twelve or fifteen feet from the water, into which it has 

 been seen to convey its young one by one, holding them 

 under the bill, and supported on its neck. The Lapps, in 

 order to supply themselves with eggs, are in the habit of 

 placing in the trees, on the banks of the rivers and lakes 

 frequented by these birds, boxes with an entrance hole, 

 which, though invariably robbed, are visited again and 

 again. 



The Golden Eye is found in many countries of Europe, 

 in northern Asia, and in JSTorth America. 



THE BUEFEL-HEADED DUCK. 



FULIGULA ALBEOLA. 



Head bluish black, with a large patch of white on the sides and back of the 

 head, the feathers of which are elongated ; back black ; scapulars, wing- 

 coverts, secondaries, and under parts wliite ; feet yellow. Length fifteen 

 inches. In the female the black is replaced by brown, feet bluish black. 

 Length thirteen inches. 



Like the Golden Eye this is a northern bird, common in 

 America, where it is called the Marionette, Spirit Duck, 

 and Conjuror, from its sudden diving at the flash of a 

 gun. It is of rare occurrence in the eastern hemispheie. 

 This species is perhaps even more active than the last, 

 which, however, it closely resembles in habits. It is said, 

 too, like the Golden Eye, to build its nest in hollow trees ; 

 but of its breeding little is known. 



In the Duck tribe generally the males exceed the 

 females in size ; but in this species the disproportion is 

 singularly great.
