This species is a not uncommon one in New England, 

 where it is found through the winter. In the more north- 

 ern districts, it is a summer resident ; and it regularly 

 breeds as far south as Massachusetts. A nest was found in 

 Cambridge, Mass., in June, 1865. It was made in an exca- 

 vation in a dead tree (or rather stump), which was carried 

 to the depth of perhaps eight inches. The nest was com- 

 posed of soft grasses, hairs, and a few feathers : these were 

 arranged compactly in the bottom of the hole to the depth 

 of perhaps an inch and a half. The eggs were six in num- 

 ber, four of them are now before me : they are ovoidal in 

 shape, of a beautiful roseate-white color, and covered more 

 or less thickly with fine spots and dashes of light-reddish. 

 Their dimensions are .80 by .61 inch, .80 by .60 inch, .78 

 by .58 inch, .75 by .57 inch. Another specimen, collected 

 in the Adirondack Mountains, is marked more sparingly 

 with coarser and darker spots : its dimensions are .70 by 

 .57 inch. 



The habits of this species are very similar to those of the 

 small woodpeckers ; and they are equally industrious Avith 

 those birds in their search for the larvge and eggs of insects, 

 which they obtain by boring in the bark, and knocking off
