black, bordered behind with white. Outer tail-feathers black, tipped and barred with white.

This industrious little bird derives its popular name from the hatches or hammerings which 

 he makes on hard nuts, in search of larvae within. It is a resident in this State, as I have 

 seen it during the whole winter. It lays from four to six whitish eggs, spotted with brown 

 at the larger end. Its food consists mainly of spiders, ants, etc. Its geographical range is 

 from Mexico to Maine.

This hardy little northern bird appears in this State in the autumn and spring, as it passes 

 to and fro on its migrations. It feeds on insects and the oily seeds of the evergreens, and 

 ranges from 38° to 52° north. Its history is as yet very imperfect, but from its resemblance 

 in appearance and general habits to the preceding, it may be presumed to be similar to that 

 species.
