On July 18th, 1887, a hen bird with a brood of chicks was found at

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
