ECOLOGY OF ISLE ROYALE. 85 



On account of tlie desolate character of this locality few birds were 

 found here. A Cedar Waxwing's nest containing five eggs was found 

 July 10. Juncos and White-throated t:?parrows were occasionally heard 

 singing among the jack pines. 



•5. Sphagnum and Spruce Bog. {Station I, 6). 



This small bog, situated on top of the hill north of Conglomerate 

 Bay, was covered with sphagnum moss and bushes with several black 

 spruce trees scattered over it. There were also several tamaracks and 

 spruce at the edge of the bog. (Fig. lIi). The birds seen, here were: 

 Golden-crowned Kinglet, White-throated Sparrow, Cedar Waxwing, and 

 Black-throated Green Wai'bler. The Oven Bird and Wilson's Thrush 

 were heard in the forest near by. 



6. Valley at Head of Conglomerate Bag {Yicinlty of Station I, 1). 



This location included the alders and the partial clearing at the 

 mouth of the brook that emptied into the head of Conglomerate Bay. 

 The partial clearing, evidently due to flre, as blackened logs were still 

 lying around on the ground, was covered with weeds, raspberry bushes, 

 dogwoods and clumps of small birches. 



The birds seen here were : White-throated Sparrow, Canadian Warb- 

 ler, Redstart, Flicker, Winter Wren, Chickadee, Nashville Warbler, Mag- 

 nolia Warbler, Olive-sided Flycatcher, Olive-backed Thrush, Sparrow 

 Hawk and Cedar Waxwing. The Redstart and Magnolia Warbler set nied 

 to be restricted to certain parts of this locality. The Redstart was always 

 seen among the alders, while the Magnolia Warbler kept among a patch 

 of evergreens at the foot of the hill on the north side of the habitat. 



III. TRIAL TO lICCAnOOE COVE. 



This station included the country along the trail which ran from 

 Rock Harbor to McOargoe Cove. This trail started on the north side 

 of the harbor at the mouth of Benson Brook wliicli it followed nearly 

 to Lake' Benson, then it crossed tlie liills to Sargent Lake and from there 

 it went to ^tlcCargoe Cove. As I did not make any observations north 

 of the Greenstone Ridge, I will only describe that portion of the^country 

 betwefen Rock Harbor and the top of the Ridge. In this portion there 

 were several different conditions which will be described in the follow- 

 ing order : 



1. Ransom Clearing (Station II, 1). 



2. Benson Brook (Station II, 1). 



8. Spruce and Tamarack Swamps (Station II, 2 and 5). 

 4. Rock Ridge Clearings (Station II, 3). 



]. Ransom Clearing (Station II, 1) . 



This small clearing on the lowland at the mouth of Benson Brook 

 was covered with grass and large clumps of alders, birches and aspens. 

 These bushes scattered through the clearing formed an excellent habitat 

 for birds, and, althougli the clearing was small, thirteen species were 

 observed here. They were as follows: Black-billed Cuckoo, Canada Jay,
