OcTOBEii,l902.] BIRDS OF KEEWATIN. 105 



Ectopistes migratorius (Linn.). Passenger Pigeon. 



Forster received a specimen from Severn River." Swainson and 

 Richardson, quoting Hutchins's manuscript, say tiiat a flock A'isited 

 York Factory in 1775 and stayed two daj-s.* James Clark Ross relates 

 that while he was crossing Bafiin Baj^ Julj" 31, 1829, on Ross's second 

 voyage, a passenger pigeon flew on board.'' Dr. Bell saw small flocks 

 on the upper part of Nelson River earlj' in September, 1878.'* Macoun 

 records a small breeding colonj^ found on Waterhen River, northern 

 Manitoba, on June 23, 1881." Tui'ner records specimens collected at 

 Moose Factory, August 16, 1860, by C. Drexler.^^ Macoun records a 

 set of eggs taken at the same place in June, 1888, bj' Mr. Miles 

 Spence,^ and Clarke records an adult pair taken at Fort Churchill 

 many years ago.'' Barnston, writing in 1840, states that the migra- 

 tor}' pigeon was frequentlj' seen during August at Martin Falls, on 

 Albany River, but disappeared about September 10. ' 



Zenaidura macroura (Linn.). Mourning Dove. 



While descending Red River from Winnipeg to West Selkirk, June 

 14, we saw several birds of this species. It is probable that it 

 regularly reaches southern Keewatin. 



Circus hudsonius (Linn.). Marsh Hawk. 



We saw five marsh hawks during our trip — the first, June 13, as 

 we were descending Red River; the next, July 13, at Beacon Point, 

 York Factory; another, August 19, at Fort Churchill; another, August 

 24, below Cape Churchill, and the last, August 29, on lower Hayes 

 River. Those observed August 19 and 24 were immature birds and 

 were secured. 



Edwards figured and described this bird, which he called the ' Ring- 

 tail'd Hawk,' from a Hudson Bay specimen.-' His figure and descrip- 

 tion form the basis of Linnseus's description of Falco hndsonhitf. 

 Murra}' recorded the species from Moose Factory and Severn River.* 



Accipiter velox (Wils.). Sharp-shinned Hawk. 



One was seen at Norway House June 19, one at Oxford House early 

 in July, and one as we were ascending Hill River September 3. 



Richardson desci'ibed a specimen from Moose Factory under the
