to June 3 (probably through May); returning late in August, and remaining 

 through the greater part of September; a small flock are said to have been 

 in the vicinity of Humber Bay all through the summer of 1905. 



23. Hydrochelidon nigra surinamensis. Black Tern. — Regular 

 migrant, May 22 to June 16, and from July 27 to September 5 (probably all 

 through May and September). A pair seen May 31, 1906, were appar- 

 ently breeding. 



24. JEstrelata hasitata. Black-capped Petrel. — I have in my 

 collection two specimens, one a male picked up dead on Toronto Island by 

 Mr. George Pierce, October 30, 1894 x ; the other taken seventeen miles 

 west on the lake shore by the late Mr. H.J. Baker, at about the same time, 

 but the date is uncertain. The first bird was in very bad condition and 

 must have been dead some days. 



The first bird is much grayer on the back and head than the second; 

 the ash-gray edging of the feathers is very pronounced on the back, while 

 in the second the edging is browner and scarcely visible, the whole back 

 being dark brown instead of gray as in the first. In the second bird the 

 crown is brown, almost black, shading to grayish brown on the back of 

 the neck, which is not divided by a white band; the cheeks and ear coverts 

 are like the crown; the feathers of the forehead are sooty brown edged with 

 white. In the first the tarsi and toes are as described, but in the second 

 they differ; the exposed portion of the tibia to just above the heel joint is 

 yellow (in the dried skin), the joint itself all around, and the back of the 

 tarsus brownish black, the front yellow, the toes and webs yellow to the 

 first joint, the rest black. 



24. Sula bassana. Gannet. — A young bird taken in 1861 at 

 Oshawa. 34 miles east of Toronto, is in the museum of Toronto University . 2 



25. Phalacrocorax carbo. Cormorant. — Accidental; one record, 

 a male taken November 21, 1896 3 . This bird was in an extremely exhausted 

 condition when found, and is the only one I have seen from anywhere on 

 the Great Lakes. 



26. Phalacrocorax dilophus. Double-crested Cormorant. — Rare 

 migrant; spring records are unusual (June 4, 1899); the majority of birds 

 examined are young, August 30 to November 1. 



27. Merganser americanus. American Merganser. — Regular winter 

 resident; the first flight occurs in September, but the bird is usually 

 resident from early in November to the end of March; latest spring 

 record, May 11, 1891. 



28. Merganser serrator. Red-breasted Merganser. — Common 

 migrant April 16 to May 7, and from October 15 to November 16; I have 

 no winter records but Mr. C. W. Nash has found this species here from 

 September 15 to April 17.
