BIRDS OF PENNSYLVANIA. 311 



webs of several primaries barred with white and dusky ; an obscure line over eye, 

 and streaks or spots on sides of head and neck whitish. 



Habitat. Eastern North America generally, breeding from the northern parts of 

 the United States northward, and wintering from about its southern breeding limit 

 southward. 



Common winter resident in southern parts of Pennsylvania from early 

 in October to about the middle of April. Breeds regularly though 

 somewhat sparingly in the northern and mountainous portions of the 

 state. During its residence with us frequents chiefly overhanging 

 banks of streams, the projecting or upturned roots of trees, brush piles 

 and dead logs in woods or thickets near watery places. The sharp 

 chirr of this sly and secretive little creature may often be heard 

 though the bird is hidden from view in wood-piles about houses, where 

 it comes to seek insects and larvae, on which it feeds exclusively. I 

 have never seen the nest or eggs of the Winter Wren. The nest is said 

 to be built generally in " thick coniferous woods," in a hole or crevice of 

 a stump or log, close to the ground, and constructed of moss, twigs, 

 lichens, lined with feathers or hair. "Eggs, five to eight, .65 by .48, 

 pure white, minutely dotted with reddish-brown and purplish" ( Coues). 



Mr. Otto Behr says (letter February, 1890) of this species in Sullivan 

 county : " The Winter Wren is quite common with us in summer, but 

 I have never seen him in the middle of winter. It is a very retiring 

 bird, never coming out in open ground in summer. He is invariably 

 found in some dark wood at the edge of a swamp. He is a splendid 

 singer, with a voice entirely out of proportion to his size, and can be 

 heard a long way off, but is rather difficult to approach. We found his 

 nest but once. It was built on the side of a mossy log that laid across 

 a small run in a dark rocky place. The nest was composed entirely of 

 moss with the entrance at one side near the bottom ; it contained six 

 eggs which resembled those of the common Chickadee. The eggs were 

 fresh ; time July 4."
