is usually placed on the ground, partly concealed by brush or 

 brushy growth. 



The Indigo-bird occurs rather sparingly in the more open 

 sections. 



The sweet, leisurely warble of the Rose- breasted Grosbeak may 

 often be heard coming from well-grown deciduous trees or from 

 lower growth, but not often from the grooves of pines or spruces. 

 Almost the same may be said of the rougher, more halting song 

 of the Scarlet Tanager. Although so strikingly colored, neither 

 of these birds is at all conspicuous on account of their keeping 

 so well hidden among the leaves. 



Although I do not know of any nesting colonies of Purple 

 Martins nearer than Portland and Stroudsburg, the birds are 

 frequently seen flying about over the plateau. 



Following their temporary sojourn in southeastern Pennsyl- 

 vania, about thirty years ago, the Cliff Swallows appear to have 

 definitely settled upon Pocono as one of their summer homes. 

 They go squeaking about, especially over the lakes, and make 

 their curious mud nests in rows under the eaves of barns. A 

 colony of thirty nests was counted last summer. 



The Barn and Rough-winged Swallows are met with regularly. 

 Nothing unusual regarding their habits has been recorded. 



The Bank Swallow is of doubtful status. I know of no nest- 

 ing colonies in the district. 



The Tree Swallows resort especially to the stumpy parts of 

 the lakes, described in the account of the grackles. The nests 

 are placed in holes in the stubs, at any distance above the water. 

 One may often look into them from a boat. A lining of feathers 

 is a normal part of the household furniture. The birds visit 

 their nests freely while the observer is only a few feet away. 



Moving about from tree to tree with their weak, beady calls, 

 or perched on the tops of the spruces with crests erect, the 

 Cedar Wax wings are as much in evidence as such quiet-colored 

 and gentle-mannered birds well could be. The rather bulky 

 nests are placed preferably in the pitch pines, on horizontal 

 branches, often over a wagon-road. They are sometimes diffi- 

 cult to distinguish from chance aggregations of pine-needles. 



Of the Vireos, the White-eyed has been noted once in early
