SYLVICULID.E — THE WARBLERS. 253 



arrival in Pennsylvania and New Jersey early in April, and its almost 

 immediate and sudden disappearance. He several times obtained tliem at 

 that period, and yet has also shot them in Louisiana as late as June, while 

 busily searcliing for food among the blossoms of the cotton-plant. 



Wilson also regarded this species as very rare. He reports it as passing 

 through reuusylvania aljout tlie middle of May, but soon disappearing. He 

 describes these birds as having niany of the habits of Titmice, and dis- 

 playing all their activity. It hangs about the e.\:tremity of the twigs, and 

 darts about from place to place with restless diligence in searcii of \arious 

 kinds of larvre. \ML3on never met with it in the summer, and very rarely 

 in tlie I'all. 



Mr. Xuttall noticed tliis species passing through Jlassachusetts about the 

 15th of April. He regarded it as an active insect-hunter, keejiing in the tops 

 of the highest trees, darting about witli great activity, and hanging from the 

 twigs with fluttering wings. One of these birds that had been wounded 

 soon became reconciled to its confinement, and greedily caught at and 

 devoured the flies that were offered. In its habits and manners it seemed 

 to him to greatly resemble the Cliestnut-sided Warbler. 



Mr. T. M. Trippe speaks of this Warbler as one of the last to arrive near 

 Orange, N. Y. Owing to the fact that at that time tlie foliage is pretty dense, 

 and that it makes but a short stay, it is not often seen. He speaks of it as 

 not quite so active as the other Warblers, keeping more on the lower boughs, 

 and seldom ascending to the tops of the trees. 



Mr. C. W. Wyatt met with this species at Naranjo, in Colombia, South 

 America. 



Eggs of this bird obtained by Mr. George Bush at Coldwater, near 

 Lake Superior, are of an oblong-oval shape, measuring .75 by .52 of an inch, 

 and except in their superior size and fewer markings might be mistaken for 

 eggs of D. a'sfirii. Their ground-color is a bluish or greenish wliite. The 

 markings are very few and fine, except those in the crown around the larger 

 end, aTid there tlie l)lotches are deeper and more numerous. Their colors are 

 dark reddish-bi'own and purple. 



Mr. Maynard found this species the most abundant of the Si/lvicolidoe at 

 Lake L^mbagog, where it breeds. Two nests were taken in June. One was 

 found June 3, in a tree by the side of a cart-path in tlie woods, just com- 

 pleted. It was built in the horizontal branch of a hemlock, twenty feet 

 from tlie ground, and five or six from the trunk of the tree. By the 8th of 

 June it contained three fresh eggs. The other was built in a similar situa- 

 tion, fifteen feet from the ground, and contained two fresh eggs. 



These nests were large for the bird, and resembled those of the Purple 

 Finch. They were camposed outwardly of fine twigs of the hackmatack, 

 with which was mingled some of the long hanging Usnca mosses. They were 

 very smoothly and neatly lined with black fibrous roots, the seed-stalks of 

 Cladonia mosses, and a few hairs. They had a diameter of about six inches,
