262 Natural History of the 



20. S. Blackburnice, Lath. (Blackburnian Warbler). — This 

 beautiful warbler was numerous about Sixteen Island and St. Jean 

 Lakes, in company with the two foregoing species, May 22nd and 

 24th. I had great difficulty in obtaining specimens, owing to its 

 extremely active habits. The skin of one shot by myself, has been 

 compared by Dr. Dawson with specimens in his possession from 

 Nova Scotia, with which it perfectly agrees, and there cannot 

 therefore be a doubt about_the species, though said to be rare in 

 the States. 



21. S. cestiva, Gmel. (Yellow-poll Wood Warbler). — Observed 

 in the Township of Grenville May 24th, and a few individuals seen 

 about Hamilton's farm August 23rd and 25th. 



22. S. Canadensis, Linn. (Black-throated Blue Wood Warb- 

 ler). — First observed at Hamilton's farm August 28th, and abun- 

 dant during the first week in September there, and at Trembling 

 Lake. About sunrise on the 23rd September, being camped on 

 the Lake of Three Mountains, and the morning cold and frosty, 

 two of this pretty warbler in company with a Wood Thrush, flit- 

 ted round our camp-fire as though envying the warmth it afforded 

 us, and this was the last date at which I observed it. 



23. S. maculosa? Lath. (Black-and-Yellow Warbler). — On 

 the 20th July when at the mouth of the Devil's River, in the first 

 Range of the township of De Salaberry, I observed a warbler 

 which I took to be this species. 



24. Certhia familiaris, Linn. (Brown Tree-creeper). — Wlien 

 I arrived at Gate Lake in the sixth range of Wentworth, on lVth 

 May, a pair of this bird were building their nest with fragments 

 of decayed wood, moss and spider's webs, behind a piece of bark 

 on a dead tree, about six feet from the ground. It is distributed 

 through the whole district, and on the 28th August at Hamilton's 

 Farm was very numerous, flitting from tree to tree in company 

 with Sylvicola coronata, S. Canadensis, Parus atricapillus, Re- 

 gulus satrapa, and Sitta Canadensis, <£c, which were then migrat- 

 ing south. 



25. Troglodytes hyemalis, Vieill. (Winter Wren). — Seen 

 occasionally during the whole summer and up to 26th Septem- 

 ber, at numerous localities throughout the district. 



2G. Parus atricapillus, Linn. (Black-cap Tit). — None of this 

 species were observed till 17th August, when camped about a mile 

 below Hamilton's Farm, and it was not numerous until the 28th, 

 when great numbers made their appearance, and I occasionally 

 observed them in the woods up to the end of September.
