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."

(A) VARius. Yelloiv-belUed Wooc^yecJcer.^^ 



(In Massachusetts, chiefly a migrant.) 



(a). About 8^ inches long. AVings and tail, black and

(c). The Yellow-bellied Woodpeckers probably occur in 

 Eastern Massachusetts as migrants only, though summer-resi- 

 dents to the westward (" bej'ond 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. The}' 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
