Errric—Birps OF A CANADIAN PEAT BoG 123 
catcher, Empidonar flaviventris, in his breeding haunts. To 
me his call sounds, oi de woit! The mosquitoes, however, 
are too thick, the spruces too dense, and the heat too great 
in the thickets, to look for nests. When going to an island in 
the bog, the only places where one may sit down without get- 
ting wet, and eat his lunch, the other members of the fly- 
catcher family may be seen, the Crested, the Pewee and even 
the Phoebe. Here also the Canadian Ruffed Grouse, Bonasa 
umbellus togata, may be flushed, and the Nashville Warbler, 
Vermivora rubricapille, heard to sing his little ditty, C/iippa 
chippa chippa chit churr, or, tshewit, tshewit, trr. Other 
common terra firma species here, are the Purple Finch, Rose- 
breasted Grosbeak, Northern Flicker, Red-eyed Vireo, Red- 
start and Black-throated Blue Warbler, Dendromica caeru- 
lescens. 
However, the thicket where lives the Yellow-bellied Fly- 
catcher harbors another interesting tenant. He announces 
himself by a very unusual song. This is a thin, high, wiry 
performance, reminding one at once of the songs of the 
Black and White, Blackpoll, and Nashville Warblers. But 
this has a queer, ventriloquial quality about it, one never 
knows where it emanates from. It sounds as if it started on 
the interior of the tree, and, rapidly accelerating, it becomse 
a little louder, as if the bird came out along the branch to 
its end. This is the Golden-crowned Kinglet, also in its 
breeding haunts. To look for a nest here, would be like look- 
ing for the proverbial needle in the haystack. The Black and 
White Warbler is found here also. 
The flycatchers, however, are not the only ones reaping a 
rich harvest from the innumerable insects flying about dur- 
ing a warm sunny day. Those past masters in the art of fly- 
ing, the Chimney Switts, Nighthawks, Barn and Tree Swal- 
lows, and even Cedar Waxwings ar found plying the same 
trade. The Barn Swallows and Swifts, of course, come from 
the adjoining farms, unless there are some hollow trees large 
enough for nesting and lodging quarters for the latter on 
one or the other of the islands; in the bog there are none.
