Willow ptarmigan complicated changes in plumage several times a year and the differing colour and pattern of the summer plumage: The willow ptarmigan often hybridises with the black grouse ("Tetrao tetrix") and the hazel grouse ("Tetrastes bonasia") and occasionally with the western capercaillie ("Tetrao urogallus"), the spruce grouse ("Falcipennis canadensis") and the rock ptarmigan ("Lagopus muta"). During the Pleistocene, the willow ptarmigan widely occurred in continental Europe. Authors who recognize paleosubspecies have named the Pleistocene willow ptarmigan "L. l. noaillensis" (though the older name "medius" might be the correct one). These marginally different birds are said to have gradually changed from the
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
