30-i The Wilson Bulletin — No. 91 



Hearing- the usual call notes one would not suspect much 

 effort, in fact, their ordinary notes, "peeh-peeh." the latter 

 slightly accented and prolonged, have none of the explosive- 

 ness of " alnorum," but are peculiarly soft, drowsy, and effort- 

 less. Remaining as motionless as possible under the inces- 

 sant attacks of " Black Flies " I soon heard the other bird 

 answering its mate, and both shortly appeared overhead, a 

 few feet distant, where they displayed mannerisms in move- 

 ment very similar to the Wood Pewee. The nest was built 

 in the hollow of a small mound, beneath the moss-cove-red, 

 protruding- portion of a root, under deep shade of young- 

 Black Spruce, Tamarack, and deciduous shrubs, with a tangle 

 of Alders in the immediate foreground, facing the open bog. 

 On the other side the growth was larger and became almost 

 entirely deciduous, mosth'' Black Birch, where the basin of the 

 bog terminated in the boulder-strewn base of surrounding 

 hills. The nest found in 1913, which I am reasonably certain 

 belonged to this species, was in a more open situation on the 

 extreme edg-'e of the small growth, in one of many mounds 

 of moss bordering- a hare-runway — almost similarly situated 

 as a nest of Nashville Warble-r found nearby. 



The exterior of nest number two had the rich brown color 

 of leaf mold, being composed of particles of dead Sphagnum 

 and other mosses, fine hair-like black rootlets, bits of decayed 

 wood, and moldy leaves. The lining was mainly of soft 

 1)leached grasses and fine black rootlets. The entire struc- 

 ture was very -looselv made with little attempt at weaving. 

 Incubation had commenced in the eggs which at fi^st sight 

 resembled those of the Alder Fh-catcher, but on com]:)arison 

 the ground color was found to be clear white against the 

 rich cream of "Alnorum." and the light reddish markings, 

 chiefly in a wreath about the larger end. were in distinct 

 contrast to the da-rker rusty red and occasional deep madder 

 brown spots of the Alder Flycatcher. They are also consider- 

 abU- smaller than those of alnorum, averaging .(iSx.53 of an 

 inch. Other species found breeding in the same bog were: 

 Yellow-throat, ATvrtle. Magnolia. Nashville, and Blackburn-
