The presence of the long gray moss on the 'trees settles the (piestion of the summer 

 ilistribntion of tliis little warbler. Wherever a tree, no matter how isolated, ap])ears 

 covered with the moss, a pair of these birds are sure to find it aud I)ree(l there. I know 

 of a cedar tree in Wayland which has no other tree near it, similarly draped witli moss, 

 which served as the home for one or two pairs of Blue Yellow-b;u'ks for several vears, and 

 they oidy gave up breeding there after the moss had blown away. 



CENUS II. DENDROICA TflE WOOD INIIABITERS. 

 Gen. Ch. Bill, shorter than the head, slender, but not very acuminate. Tarsus, lunger than the 

 middle toe and claw. Height of keel, a little exceeding one-half the width of sternum but not as high as in 

 the preceeding genus. Coracoid hones, shorter in length than the top of the keel.

DESCRIPTION. 



Sp. Ch. Form, rather robust. Size, large. Bill, stout and conical. Feet, wings, and tail of moderate 

 size, the latter emarginate, with white sjiots confined to two pairs of outer feathers. Sternum, stoutly 



built. The keel is considerably higher than one-half the width of 

 the sternum in comparison with other members of the genus. 

 Tongue, narrow, thin and quite acuminate, with the end divided 

 into rather coarse cilia about three-hundredths of an inch in length, 

 which extend along the sides, growing gradually shorter until they 

 disappear, occupying about one-fourth of the terminal length. 



Color. Adult male. Above, olivaceous green, brightest on 

 the back and palest on the upper tail coverts, with the feathers of 

 the top of the head showing darker centers. Wings, dark brown 

 with the two rows of wing coverts tipjHjd with white, and formin"- 

 bai's. Tail, also brown but liaving spots of white on the inner webs 

 of the two outer pairs of feathers, which seen from above, extend on 

 the outer terminal portion of feather, along the vein usually not quite in contact with it, excepting for a small, 

 terminal spot, about one-half the length of the feather, also along outer web from bases to more than one-half 

 the length. Beneath, this feather is wholly white on outer web, also on ternunal portion of inner. The 

 •white on the second pair of feathers is not m )re than half as extended, and does not come in contact with the 

 vein anywhere. See Fig. 87 for form of this spot. The feathers of the wings and tail are also slightly edged 

 with whitish. Throat, breast, sides and flanks, yellow, but liecoming paler (ju the latter. Abdomen, under 

 tail coverts and under wing coverts, white. Lores, dusky. There are also dusky lines along the sides caused 

 ty the feathers having darker centers. In autumn there is a bluish white washing above : the yellow 

 beneath is a little more extended ; the dark lines on the sides are not as conspicuous, but the lores and the 

 ear coverts are quite dusky. 



The voung male is somewhat like the autumnal adult but there is a brownish cast to the washin''
