Mr Xnttall .le.scrihes a nest of this hini, Im.nd by him snspend.d from the 

 orked twig ol an oak, near a dweliin-house, as cated over with -reen 

 hehens attaehed very artfnlly hy a slender string of eaterpillars' silk^ tlu, 

 whole afterwards tied over hy alnu.st invisible threads ol' the same so niixdv 

 done as to appear to be glned on. The whole fabric was thus ma,le to rJ- 

 semble an accidental knot, of the tree, grown o^•er with moss. Another nest 

 observe.1 by the same writer, was fixed on the depen.ling branches of a wild 

 cherry and was fifty feet from the ground. So lofty a position as this is 

 probably very unusual. I have never met with any higher than ten feet 

 irom the ground. 



The food of this Vireo is chiefly insects, and in the breeding-season is 

 a]to.g« her so. Later in the season they .mingle with these various kinds of 

 small berries. 



The eggs of this species vary from .95 to .SS of an inch in length, and 

 from .65 to .60 in breadth. Their ground-color is white, often with a very 

 percep ible tint of ro.seate Avhen fresh. In this respect they differ in a very 

 marked nianner from the eggs of any other of this genus, except, perhaps, 

 the bnrbatnla, and may thus always be very easily recognized. They are 

 more or less boldly marked with blotches of a dark r.jseate-brown, also pe- 

 culiar to the eggs of this species, though varying greatly in their size and 

 depth of color. 



This Vireo winters, in great numbers, in Central America, and was lar-ely 

 represented in the collection of Dr. Van Patten from Guatemala. It was 

 also found at Tirico, in Colombia, South America, by Mr. C W Wya't 

 It occurs in abundance as far to. the west as Crinnell, Iowa, where Mr." 

 W. H. Parker found it to be a very common summer resident.
