248 FLYCATCHERS. 



To thoroughly appreciate how well the Pewee's disposition is 

 suited to his haunts and notes, we have only to imagine him taking 

 the Phoebe's place and singing the Phoebe's song. lie was not in- 

 tended to adorn a bridge or barn, but in the darkened woods, high up 

 in the trees, he finds a congenial home. 



His pensive, gentle ways are voiced by his sad, sweet call : 



fy The notes are as musical and restful, as much a part 



of Nature's hymn, as the soft humming of a brook. 



\ > ^^~~r All day long the Pewce sings ; even when the heat 



L Z^ of summer silences more vigorous birds and the 



Pee-a - wee midday sun sends light-shafts to the ferns, the 



clear, sympathetic notes of the retiring songster come from the green 



canopy overhead, in perfect harmony with the peace and stillness of 



the hour.

 tree or imbedded in moss. ffff<j, four, creamy white, with numerous pale cin-

To see this little Flycatcher at his best, one must seek the northern 

 evergreen forest, where, far from human habitation, its mournful 

 notes blend with the murmur of some icy brook tumbling over mossy 

 stones or gushing beneath the still mossier decayed logs that threaten 

 to bar its way. Where all is green and dark and cool, in some glen 

 overarched by crowding spruces and firs, birches and maples, there it is
