in keeping with the wildness of its haunts; others may excel it in 
more definable vocal qualities, but “ None sing so wildly well.” 
FAMILY MNIOTILTIDSE: AMERICAN WARBLERS. 
As represented in the Catskills, the Mniotiltidse 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 Helminthophila 
ruftcapilla Ridgw. is of probable occurrence; Dendrceca pinns Baird, less so, 
while several others are not improbably occasional summer residents. 
Muiotilta varia (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 (. Helminthophila pinus 
Ridgw.) is given by Giraud,* under Audubon's name of Helinaia 
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 Americana (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. 
Dendrceca lestiva (Gm.) Baird. Summer Yellow Warbler. 
Seemingly confined to the immediate vicinity of the dwellers’ cot- 
tages in the valleys, and noticed on three or four occasions only. 
Dendrceca ccerulescens (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
