FAUNAL roSITlON. ^^ 



Warblers; White-winged and Red Crossbills. White- throated Sparrow, 

 junco, Rusty Blackbird, Raven, Canada Jay, Olive- sided Mycatcher, 

 Black-backed and Banded-backed Three-toed W^oodpeckers, Spruce 

 Grouse, Goshawk, and Golden-eyed Duck. In addition to the above 

 it is not improbable that the Hudsonian Tit and one (or both) of the 

 Kinglets will be found nesting here. 



Mention of the characteristic Reptiles, Batrachians, and Fishes is 

 deferred, and will be made in the chapters pertaining to these groups. 

 Following is a list of " Subarctic " species of Lepidoptera collected 

 in the immediate vicinity of Beaver Lake (also called " Fenton's," and 

 " Number 4") in Lewis County, by Mr. Hill, and identified by Prof. 

 J. A. Lintner, late State Entomologist : Agrotis CJiardinyi, A. con- 

 jlua, A. astricta, l^lusia biniacalata, I\ u-aurcuvi, 'riiannioiuviia brun- 

 ncata, Mclanippc haslata, M. Jhictiiata, Corcniia fcrruoaria, Cidaria 

 Packardata, C albolincata, C. cuuiocrata^ C. hcrsiliata, C. tniucaiiu 

 Sparoauiia viagnoUata, Oporabia cauibn'can'a, and Laroilia C(csiata. 

 These were all found in a single locality, and therefore probably con- 

 stitute but a small proportion of the northern Lepidoptera that occur 

 in the Adirondacks. 



Moral limitations are by no means so clearly defined as the boun- 

 daries of Faunal areas, and for the reason that plants are much more 

 easily than animals affected by minor physiographical conditions. 

 They are more susceptible to the influences of local topographical and 

 climatic conditions, such as altitude, humidity, etc., and are also 

 affected by the nature of the soil, and by association with one another. 

 This is seen in the influence which certain kinds of forests exert in 

 determining the character of the more humble plants that orow in 

 their shade. Vox examj^le. it is well known that the destruction of 

 an exergreen coniferous forest is commonly followed, in the course of 

 nature, by a growth of hard timber— maple, beech, and birch (all decid- 

 uous trees) usually predominating. Coincident with this change of 

 lorest is an equally radical change in the kinds of small plants that 

 spring up underneath.
