Towhee, singing and working in tlie shrubbery ; Chipping Sparrow,

nesting and feeding young; Golden- winged Warbler, singing and

The Base of Bear Mountain. The base of Bear Mountain has 
been defined as the portion of bushy and wooded hillside immedi- 
ately above the roadway leading from the office building of the Inn 
grounds toward the interior of the Park. The central spot of this 
basal area under consideration might be marked by the point where 
the trail up the mountain begins, designated by a small signboard 
marked with the legend, “ To the Top of Bear Mountain ”. Below 
this designated point, on the left as one follows the trail, a ravine 
formed by a narrow watercourse comes down from the southeast. 
On the right, above the watercourse, the hillside is thick-set with 
laurel, purple-flowering raspberry, blackberry, witch hazel and vibur- 
num, with clumps of sapling maple, chestnut, oaks and hickories, 
under a ragged canopy of characteristic hardwood trees (Fig. 6). 
From the sign, “ To the Top of Bear Mountain ”, as a center, the 
activities of most of the birds of the Bear Mountain locality can 
be studied by merely standing observant with watchful eyes and 
keen ears; mentally I characterized this spot as “Warbler Point” 
(Fig. 7), for there I made close observations concerning the 
Golden-winged Warbler, Cliestnut-sided Warbler, Yellow-breasted 
Chat, Hooded Warbler, Worm-eating Warbler, besides others more 
common and better known. Taking my notes in chronological 
order, I made observations on this basal hillside as follows : Indigo 
Bunting, singing, nesting and feeding young; Towlree, singing, 
nesting and feeding young; Red-eyed Yireo, singing, nesting and 
feeding young; Chestnut-sided Warbler, singing, nesting and feed- 
ing young; Maryland Yellow-throat, singing and feeding young; 
Hooded Warbler, singing and nesting; Oven-bird, singing and 
nesting; Ruby-throated Hummingbird, active among the flower- 
ing shrubs; Yellow-breasted Chat, singing and nesting in the 
laurel; Golden-winged Warbler, singing and active in the trees 
and saplings; Worm-eating Warbler, singing, nesting and feeding
