in keeping- with the wildness of its haunts; others may excel it in 

 more definable vocal qualities, but " None sing so wildly well." 



FAMILY MNIOTILTID^: AMERICAN WARBLERS. 



As represented in the Catskills, the Mniotiltidae constitutes an important 

 definitive element of the Avi-fauna, and is the most numerously represented 

 family of birds in species, and doubtless also in individuals, of the region. 

 Notwithstanding that seventeen species are enumerated as occurring, it is 

 probable that several others will have to be added; while some half a dozen 

 species which faunal limitations exclude from the mountain region proper, 

 regularly breed in numbers in the adjacent Hudson Valley. These have 

 already been named. Of species which were not observed HchnintJiophila 

 ruficapilla Ridgw. is of probable occurrence; Dcndra\'a piniis Baird, less so, 

 while se\'eral others are not improbabh' occasional summer residents. 



Muiotilta raria (L.) Vieill. Black-and- White Creeping Warbler. 



Frequent in the woods along the valley, but not extending far into 

 the mountains. 



Note. — The Blue-winged Yellow Warbler iyHcbnintJiopJiila pinus 

 Ridgw.) is given by Giraud,''' under Audubon's name of Hclinaia 

 solitaria, as having " been shot during summer on the Catskill Moun- 

 tains." Even if this bird was found in the mountainous portions of 

 the Catskills it can hardly be considered as more than a straggler 

 there; but we may be allowed to suspect that the capture referred to 

 was on some of the outlying hills or the lowland bordering the Cats- 

 kills proper. 



Parula Americaua (L.) Bp. Blue Yellow-backed Warbler 



Not uncommon in the wooded valleys, and noticed in the moun- 

 tains up to about 2,700 feet altitude. 



Dendroeca aestiva (Gm.) Baird. Summer Yellow W^arbler. 



Seemingly confined to the immediate vicinity of the dwellers' cot- 

 tages in the valleys, and noticed on three or four occasions only. 



Dendroeca coerulesceiis (L.) Baird. Black-throated Blue Warbler. 



Between the lower parts of the valleys and the higher elevations 

 of the mountains this warbler seemed to be generally distributed in
