1^4 T'he Ottawa Naturalist. [December 



middle of June, I determined to make a final effort to find the nest 

 it it was in that vicinity. Soon after "1 had entered the thicket, 

 both birds g-reeted my intrusion by notes of disapproval. I then 

 felt certain that a nest was near, and probably contained youngf ; 

 but again though every leafy bush and clump of dry leaves, even 

 of those on the ground was examined, but no nest could be dis- 

 covered, still the birds continued their excited scold, and came 

 quite near. On one side of the thicket stood the turn up root 

 of a large fallen tree, and when ever/ other spot likely to contain 

 a nest had been examined in vain, I turned my attention to this, 

 and glancing upwards from my position on the ground, I caught 

 sight of a nest. This was partly suspended, and partly supported 

 among the rootlets of the " turn-up," but quite concealed from the 

 observation ot a person standing on the ground even when 

 close by by a portion of soil which still adhering to some of the 

 longfer rootlets hung downwards, and over the site of the nest. 

 On looking close at this nest I found that it contained four young, 

 almost ready to fly. 



In the early days of June, 1896, I found another nest of this 

 species in the same woodland : but in a situation that I would 

 never have supposed this bird would have nested in. In the 

 deepest part of the wood, but near its eastern edge, a large red- 

 maple tree had blown down, and in its fall it took down a smaller 

 hemlock tree that stood in its way, the " turn-up " which was 

 elevated only about two feet above the hollow out of which it had 

 been torn, and beneath this was a small cave-like chamber, such 

 as a winter-wren or a phoebe would chose to nest in. Looking 

 into this one day, I discovered a nest placed on some rootlets, 

 which at first sight I took to be that of the latter-named fly- 

 catcher, but a little examination showed that this nest, and the 

 two eggs which it contained, were those of a black-throated^blue 

 warbler. Two days after I revisited this nesting site, but no 

 more eggs had been deposited, and no bird was there, it had 

 evidently been forsaken, but the situation was a very strange one 

 for a member of this genus to select for a nesting place. Up to 

 the close of the season of 1902, no other nests of this species have 

 been noted, and the bird is now quite rarely observed in this 

 vicinity.
