‘that of a species of tree-frog which frequents the same tree, 
that it is sometimes difficult to distinguish the one from the 
other.” 
Wilson eloquently defends this bird, proving his beneficial 
nature. He adds: ‘*The Red-headed Woodpecker is, properly 
speaking, a bird of passage; tho even in the eastern states 
individuals are found during moderate winters, as well as in 
the states of New York and Pennsylvania; in Carolina they 
are somewhat more numerous during that season; but not one 
tenth of what are found in summer. They make their appear- 
ance in Pennsylvania about the first of May; and leave us 
about the middle of October.”

(In Massachusetts, chiefly a migrant.) 
(a). About 83 inches long. Wings and tail, black and 
white. Above, brownish or yellowish, marked with black. Be- 
neath, yellowish ; sides black-streaked. Crown-patch, scarlet ; 
throat-patch, scarlet, or in Q whitish. Border of both patches, 
and eye-stripe, black. Head otherwise white or yellowish.

(c). The Yellow-bellied Woodpeckers probably occur in 
Eastern Massachusetts as migrants only, though summer-resi- 
dents to the westward (‘‘ beyond Springfield”), and to the 
northward, as in Canada, or the northernmost parts of New 
England, where they are quite common. Near Boston, I have 
seen them about the middle of April, and again in October, 
but I have always found them rare. They are somewhat shy, 
and usually silent. They travel singly or in pairs, and fre- 
quent woods rather than orchards. I have seen a pair, how- 
ever, on a pine-tree, so near a house, that they were fired at 
with a parlor-rifle from the windows. As each bullet struck
