 (Brooks.) Chapman refers summer specimens collected by Osgood 

 at Glacier bay and White pass to true leucurus, Cook inlet specimens 

 to peninsular is. 



Breeding Notes. — This species was found on the summits of 

 all the western mountains which have been ascended by the writer. 

 On July 1 8th, 1887, a hen bird with a brood of chicks was found at 

 an altitude of 6,000 feet on Mount Arrowsmith, Vancouver island; 

 on August 8-1 2th, 1889, numerous broods were seen on the Gold 

 range, B.C., at an altitude of 7,500 feet; on August 24th, 1885, three 

 large broods were seen on the summit of Avalanche mountain, 

 near Glacier, B.C.; and lastly a brood was seen on the summit of 

 Sulphur mountain, close to Banff, Rocky mountains, on September 

 ist, 1897. In all the cases cited, the birds were quite tame and the 

 chicks had no apparent fear. In only one case was the nest found. 

 It was a slight depression by a large stone with a lining of grass and 

 a few feathers.

Tympanuchus americanus (Reich.) Ridgw. 1886. 



In the first week of May, 1886, one specimen was shot on Hamilton 

 beach ; from various sources I have learned that this species is still 

 seen along the southwestern frontier of Ontario, but their numbers 

 are decreasing. (Mcllwraith.) Mr. Fleming does not believe that 

 the specimen recorded by Mcllwraith was a native bird or that it 

 ever came as far east as Lake Ontario. Mr. E. T. Set on in his Birds
