188 ORNITHOLOGY AND OOLOGY. 



the moss and dead pieces of trees with their sharp, powerful 

 bill. 



In traversing the limbs of trees, they resemble in their 

 movements the Downy Woodpecker ; and their flight is also 

 similar to that bird's. The note is a short, harsh call, simi- 

 lar to the syllables cJia-cha-c7ia-chd, uttered quickly, and with 

 emj^hasis.

The same remarks as to distribution, habits, <fec., will 

 apply to this species as to the preceding. It is quite abun- 

 dant as a summer resident in the wilds of Maine; and its 

 notes are almost the first sound heard by the traveller on 

 awakening in the early morning. I have sometimes heard 

 its note in the night, while floating in my canoe on the 

 bosom of some tranquil lake or between the banks of a 

 sombre river ; and frequently they seemed to be high up 

 in the air, as if the bird had taken flight. These notes 

 are a sort of drawling repetition of the syllable chape, like 

 perhaps the following : Cheadpe, cheadpe, cheadpe. 



The nest is built in a hole in a tree or stump, usually 

 excavated by the birds for the purpose : it is of the same 

 'description as that of the preceding, as are also the eggs 

 with the exception of size ; the present being considerably 

 smaller, averaging .64 by .53 inch. 



Audubon, in describing the nest of the Red-bellied Nut- 

 hatch, says, —
