682 Mr. C. B. Horsbrugh : Ornithological Notes 



Tympanuchus americanus americaniis. Prairie Chicken. 



A fairly common species and very tame during the nesting- 

 season, but wild enough soon after the shooting-season 

 opens. 



Zenaidura macroura macronra. Mourning Dove, 



I received a specimen from Mr. George Cook, which he 



shot at Buffalo Lake on November 9. He states that it is 



very rare and this was the only one seen. 



Circus hudsonius. Marsh Hawk. 



May 13 is my first record for this species, which later 

 in the season may daily be seen flying over the sloughs in 

 search of prey. I received a young male in the flesh on 

 September 17. 



Accipiter velox. Sharp-shinned Hawk. 

 I received an immature male bird on October 6 which was 

 shot near Alix. The species seems rare in this district. 



Astur atricapillus atricapillus. Goshawk. 



I first observed this species on May 15, flying over a lake 

 near our house. A fine specimen boldly flew into our poultry- 

 yard on October 15, but did no damage to the chickens. 

 I shot an immature bird on the 28th which also came to 

 worry the poultry. A nice male specimen, shot at Alix, 

 was presented to me on November 26. 



Buteo borealis borealis. Red-tailed Hawk. 



In a small copse bordering a large grassy slough I found 

 a nest of this species on May 9. It was placed in a 

 straight poplar about 35 feet from the ground and contained 

 three eggs, dullish white slightly blotched with pale red 

 markings, and well incubated. The birds were very noisy, 

 and kept in the vicinity until we left. 



On June 21, shortly after my wife and I almost drove 

 over a brood of young Buffel-headed Ducks (see notes under 

 that species), we saw a Red-tailed Hawk evidently searching 

 for them. A pair were flying round the house on August 17,
