2. Colymbus auritus. Horned Grebe. — Common resident in spring 

 and fall, March 14 to April 23 (probably to May); and from middle of 

 September to end of November (October 27, 1896). Spring birds are 

 in full plumage, or nearly so, when they arrive. 



3. Podilymbus podiceps. Pied-billed Grebe. — Common resident 

 in spring and fall, April 4 to end of May; September 7 to December 15. 

 Mr. C. W. Nash took a male June 28, 1898; and it has been reported as 

 breeding. 



4. Gavia imber. Loon. — Regular migrant, April 16 to May 31 

 (abundant May 22, 1894); earliest fall record, September 7, 1895; a bird 

 taken October 19, 1904, is young, and one taken November 4, 1899, is an 

 adult in winter plumage. Loons probably remain on the lake till the end 

 of November. 



5. Gavia lumme. Red-throated Loon. — Regular migrant, not 

 uncommon; adults in breeding plumage, April 28 to June 3; earliest 

 record a male in winter plumage, March 14, 1899; in fall from October 6 

 to November 30. There are no winter records. 



6. Cepphus grylle. Black Guillemot. — One record, a female taken 

 December 19, 1895. It is possible that this bird is C. mandtii, as its 

 beak is small, and the plumage very white. The specimen is in a sealed 

 case and a closer examination is necessary. 



7. Uria lomvia. Brunnich's Murre. — In 1893 this species entered 

 Lake Ontario in considerable numbers; the first appeared at Toronto 

 November 29, and they increased in numbers through December, all event- 

 ually dying of starvation. For the next ten years the birds were noted 

 annually in November and December, but in decreasing numbers, none 

 surviving very long. The migration of this maritime species into the fresh 

 waters of the Great Lakes was so remarkable and accompanied by so many 

 unusual features that I have recorded elsewhere a fuller account. 1 



8. Alca torda. Razor-billed Auk. — One specimen taken Decem- 

 ber 10, 1889, now in the Canadian Institute. 2 There is also a Hamilton 

 record in the collection of Mr. John Maughan, Jr., taken December 9, 1893. 



9. Alle alle. Dovekie. — One record, a female taken November 

 18, 1901, 3 in collection of Mr. John Maughan, Jr. 



10. Stercorarius parasiticus. Parasitic Jaeger. — Of regular 

 occurrence, rare; adults taken June 20, 1891, and October 20, 1894; both 

 in the light phase of plumage, the latter not quite adult. I have examined 

 six local specimens and as many more from other points on Lake Ontario 

 and Lake Erie; the majority are immature in the dark phase, and only one, 

 a Toronto bird, is in the light phase of plumage.
