TOWNSEND AND ALLEN: LABRADOR BIRDS. 407 
Dendroica caerulescens (Gmel.). 
BLACK-THROATED BLUE WARBLER. 
The only record is that of the finding of a dead bird by Audubon 
(’35, p. 309): ‘In Newfoundland I saw none, and in Labrador only 
a dead one, dry and shrivelled, deposited like a mummy in the fissure 
of a rock, where the poor bird had fallen a victim to the severity of the 
climate.” 
Dendroica coronata (Linn.). 
YELLOW-RUMPED WARBLER; MyrtTLE WARBLER. 
Common summer resident, chiefly in the Canadian zone. 
Audubon states that this was among the first birds observed by him 
in southern Labrador. Stearns says it is ““common in interior. 
Breeds.” Frazar saw four on one day in July at Cape Whittle, and 
Low records a “‘specimen from Grand Falls, Hamilton River, May 
31st.”’ 
Dendroica maculosa (Gmel.). 
MaGNoutia WARBLER. 
Common summer resident in the Canadian zone. . 
Audubon found a nest with five eggs of this species in southern 
Labrador in the beginning of July, and in the first days of August he 
saw many young following their parents. Low says it is “not rare 
at Lake Mistassini,” where it arrives the last of May. 
Dendroica castanea (Wils.). 
BAY-BREASTED WARBLER. 
Very rare summer resident. 
Turner records that ‘‘three individuals were seen at Black Island, 
Hamilton Inlet, by me July 9, 1882. Two were shot, but lost in the 
thick undergrowth; one of the birds was actually in my hand, but 
escaped.” It is a bird of the Canadian zone and has been taken 
just outside of the limits of Labrador at Moose Factory.
