It was later determined that "Lagopus" had sufficient distinguishing features to be regarded as a separate genus and the bird became "Lagopus leucurus". Molecular studies have shown that "Lagopus" is monophyletic, with the rock ptarmigan ("Lagopus muta") and White-tailed ptarmigan being sister species. The position of the willow ptarmigan ("Lagopus lagopus") is less clear cut, it showing some genetic divergence over its wide range. The genus name "Lagopus" is derived from Ancient Greek "lagos" (λαγως), meaning "hare", + "pous" (πους), "foot", in reference to the bird's feathered legs.
Ptarmigan (sternwheeler) surface). Captain Armstrong was able to raise "Ptarmigan" and return her to service. However "Ptarmigan" caught fire later in 1907, and her upper works were destroyed. Again, "Ptarmigan" was salvaged, her upper works were rebuilt and she was returned to service. The gasoline engine was a new development in the early 1900s. Captain Northcote Cantlie, who has gone down in history as "an eccentric Scot" purchased a gasoline-engined launch, "Gian", and placed her on the upper Columbia. Unlike Armstrong, Cantlie came from a wealthy background, drank champagne for breakfast, and kept a bagpiper as his personal attendant. Cantlie, knowing that
