curved glidings. When ascending, however, it becomes as it were uncertain 
and angular. 
The Orange-crowned Warbler breeds in the eastern parts of Maine, and in 
the British provinces of New Brunswick and Nova Scotia. Its nestis com- 
posed of lichens detached from the trunks of trees, intermixed with short 
bits of fine grass, and is lined with delicate fibrous roots and a proportionally 
large quantity of feathers. The eggs, which are from four to six, are of a 
pale green colour, sprinkled with small black spots. The nest is placed not 
more than from three to five feet from the ground between the smaller forks 
of some low fir tree. Only one brood is raised in the season, and the birds 
commence their journey southward from the middle of August to the 
beginning of September. 
In autumn, it nearly loses the orange spot on its head, there being then 
merely a dull reddish patch, which is only seen on separating the feathers. 
In the breeding season the part in question becomes as bright as you see it 
in the plate, in which are represented a pair of these birds on a twig of the 
great huckleberry. The young do not shew any orange on the head until 
the following spring.
