RED-EYED FLYCATCHER. 133 
set in cold, they disappear from Pennsylvania, directing their course 
to the south, At this time they swarm among the rice fields; and 
appear in the island of Cuba in immense numbers, in search of the 
same delicious grain. About the middle of October, they visit the 
island of Jamaica in equal numbers, where they are called Butter 
Birds. They feed on the seed of the Guinea grass, and are also in 
high esteem there for the table.* 
Thus it appears that the regions north of the fortieth degree of 
latitude, are the breeding places of these birds; that their migrations 
northerly are performed from March to May, and their return southerly 
from August to November; their precise winter quarters, or farthest 
retreat southerly, are not exactly known. 
The Rice Bunting is seven inches and a half long, and eleven and 
a half in extent. His spring dress is as follows: — Upper part of the 
head, wings, tail, and sides of the neck, and whole lower parts, black ; 
the feathers frequently skirted with brownish yellow, as he passes into 
the colors of the female; back of the head, a cream color ; back, black, 
seamed with brownish yellow; scapulars, pure white; rump and tail- 
coverts the same; lower part of the back, bluish white; tail, formed 
like those of the Woodpecker genus, and often used in the same man- 
ner, being thrown in to support it while ascending the stalks of the 
reed; this habit of throwing in the tail it retains even in the cage; 
legs, a brownish flesh color; hind heel, very long; bill, a bluish horn 
color; eye, hazel; see Fig. 47. In the month of June this plumage 
gradually changes to a brownish yellow, like that of the female, (Fig. 
48,) which has the back streaked with brownish black; whole lower 
parts, dull yellow; bill, reddish flesh color; legs and eyes as in the 
male. The young birds retain the dress of the female until the early 
part of the succeeding spring; the plumage of the female undergoes 
no material change of color.

Tuis is a numerous species, though confined chiefly to the woods 
and forests, and, like all the rest of its tribe that visit Pennsylvania, is 
a bird of passage. It arrives here late in April; has a loud, lively,
