.SYLVR'OLID.K — THE WAKBLEIW. 229 



This Warbler is an expert Hycatcher, feeds eliieHy on insects, and is a great 

 (levourer of small caterpillars; !)Ut in tlie winter its food is larj^ely (•i>mi»)setl 

 of herries, especially llujse of the Mi/riin vii-l/tni. It will also feed on grass- 

 seeds. In the warmer wintry days in Florida, when insects are aliundant, 

 Mr. Audubon states that these birds are particularly active in their pursuit, 

 and the trees seem full of them. At this time they endt, at each movement, 

 a single note, ticeet, so very jieculiar that they may be at once recognized by 

 the cry. 



Wilson states that these Warblers a])pear in Pennsylvania, from the North, 

 early in October, and stay there s(!veral weeks. Some of \.\\v.n\ lemain in 

 the Southern States all winter. They feed witli great avidity upon the ber- 

 ries of the red cedar. 



In Western Mas.sacinisetts it is a very al»undant spring and autumn visit- 

 ant, making but a brief stay in sjiring, Imt pa.ssing northward in large num- 

 bers. In autumn it remains longer, and passes south more leisurely. Mr. 

 1>. P. Mann found its nest and eggs in Coiicord, but this was jirolialily an ex- 

 ceptional instance. In Eastern Maine it arrives May Ho, and, as Mr. ]>oard- 

 man thiidss, remains to breed. Both Dr. Suckley and Dr. Cooper met with 

 this .sp(icies in Washington Territory, where it is very rare. 



No writers have observed or noted tlie song of this l)ird, except Mr. T. ^I. 

 Trippe (American Nat., II. [). 171), who states that iluring its si)ring migra- 

 tions it lias a verv sweet song or warl)le, uttered at siiort intervals. 



It reaches the high northern latitudes hiti' in May, and leaves that region 

 in September. The observations tif Mr. McKarlane show tiiat the nests of 

 this bird are moderately common at Anderson lliver, and are generally liuilt 

 in low spruce-trees four or five feet from the ground. In one or two 

 instances it was placed on the ground. 



Tlie eggs of tliis AVarbler vary from .71' to .SO of an inch in lengtli, and 

 from .no to ..").") in breadth. Their ground-color is wiiite, often tinged witii a 

 blui.sh shade, and lilotched and s]iotte(l with reddisji-ln'own, puri)le, and darker 

 shades of brown. They are of a ro.'ided oval shape.
