White-tailed ptarmigan name "Tetrao (Lagopus) leucurus" by the Arctic explorer John Richardson in 1831. 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) "Gian" was at least theoretically faster than "Ptarmigan" made several challenges to Armstrong to race. There is a story that one day in late August 1906 Cantlie was out in his launch in the river at the same time as "Ptarmigan". Cantle seized the moment and sped past "Ptarmigan" with his bagpiper blasting out airs as "Gian" sped past. This was too much for Captain Armstrong, a master steamboat man and veteran of the Klondike Gold Rush. Armstrong ordered full steam ahead, and when "Ptarmigan" caught up to "Gian", two or three roustabouts reached over to "Gian", seized the still-playing
