MOURNING WARBLER BREEDING AT TORONTO. 



July i, 1893. — In a very thick swampy spot up the Don 

 River I saw a pair of Mourning Warblers (Geothlypis Phila- 

 delphia) that appeared to be very much excited and annoyed at 

 the presence of my dog. On my going to the spot, the male 

 warbler dropped to the ground and ran ahead of us with its 

 wings half raised. I caught the dog and searched carefully, 

 and found a young bird still in the downy plumage. It ran well 

 and hid cleverly, but at last I caught it. The female did not 

 come very close to me until I actually had the young one in my 

 hand, and then only for a moment ; she seemed to be attending 

 on other young in the bushes a short distance away. 



July 2. — Caught the male parent of my young Mourning 

 Warbler in a trap cage by using the young one as a decoy. 

 Whilst he was about the trap a Hawk (Broad-winged) dashed 

 at him, and alighted on the spot the Warbler seemed to occupy, 

 but the Warbler in some way slid from under the Hawk's 

 claws, and ran into the thick bushes and escaped that danger. 



July 26. — The young Mourning Warbler which I am raising 

 is now showing some clear yellow along the sides of the breast 

 and under the tail ; hitherto the head, neck and back have been 

 brown ; the tail, primaries and secondaries olive green ; chin 

 and throat brown, and breast and belly pale yellowish brown ; 

 feet and tarsi flesh color ; the bird is very active and tame, and 

 bathes every day. 



August 11. — The young Mourning Warbler is now fully 

 fledged and very active, but shows no sign of black on the 

 throat or ashy blue on the head ; it catches flies on the wing 

 with the greatest ease and certainty, and is very fond of all 

 kinds of succulent green leaves.
