>IRDS of this Genus have a slender and weak bill.* 



Nostrils small, a little depressed. 



Tongue, in general, cloven. 



The exterior toe joined, at the under part, to the base of the 

 middle one. 



This Genus, and that of the Wagtail, are blended by Linnaeus; 

 but are here separated, from their differing in manners. 



Warblers perch on trees for the most part, and proceed by leaps, 

 rarely running,f and seldom emit any noise in flight : they are most 

 numerous of any, and the greater part inhabit the warmer regions, 

 where insects of all kinds abound, on which they principally feed. 

 Some birds, included under the head of Warblers, seem allied to the 

 Flycatchers, and perhaps, when more fully known, may prove to 

 be such. 



We have made every effort, in respect to the above numerous list, 

 to discriminate the several Species as such ; but it must not be won- 

 dered at, if many, supposed to be distinct, may hereafter prove to be 

 merely Varieties, or incomplete in plumage; or that several, from 

 our present incomplete knowledge of them, may have been described 

 twice, under different appellations.

* In many, there is a slight notch near the tip of the under mandible, 

 j- The Wheatear, and some few others, are an exception to this.
