174 SYLVICOLID^E : AMERICAN WARBLERS. 



A common summer resident of New England, arriv- 

 ing early in May, and leaving in September. It breeds 

 more numerously in the Canadian Fauna than else- 

 where, and this appears to be the limit of its northward 

 dispersion. It has been supposed to be confined to 

 this Fauna in the breeding season, but such proves not 

 to be the case, various nests having been found in 

 Massachusetts, and the birds themselves all through 

 the summer in Connecticut. A nest taken with eggs 

 in Lynn, Mass., was placed on the ground at the foot 

 of a grass-clump, in a low swampy piece of ground, 

 and was built almost entirely of 

 the needles of the white pine, 

 so loosely disposed that it was 

 found necessary to sew them to- 

 gether in order to preserve the 

 structure. The eggs were five 

 in number, white, irregularly 

 marked with dots and small 

 blotches of reddish-brown, after

 eggs, measuring 0.75 by 0.56 



of an inch. Another ground-nest, at first supposed 

 to belong to the Red-bellied Nuthatch, but afterward 

 identified as probably built by the present bird, has 

 been described by Mr. F. H. Nutter (Am. Nat., xi, 

 l8 77> P- 565 ; xii, 1878, p. 397) ; this was from West 

 Roxbury, Mass. Such method of nesting seems to be 

 common to all our members of the genus Wilsonia, 

 or MyiodiocteS) as of the genus Helmintkofhaga ; 

 being very different from the case of Setophaga.
