Rock ptarmigan (Lagopus muta) and willow
ptarmigan (L. lagopus) are Arctic birds with a circumpolar
distribution but there is limited knowledge about their
status and trends across their circumpolar distribution.
Here, we compiled information from 90 ptarmigan study
sites from 7 Arctic countries, where almost half of the sites
are still monitored. Rock ptarmigan showed an overall
negative trend on Iceland and Greenland, while Svalbard
and Newfoundland had positive trends, and no significant
trends in Alaska. For willow ptarmigan, there was a
negative trend in mid-Sweden and eastern Russia, while
northern Fennoscandia, North America and Newfoundland
had no significant trends. Both species displayed some
periods with population cycles (short 3–6 years and long
9–12 years), but cyclicity changed through time for both
species. We propose that simple, cost-efficient systematic
surveys that capture the main feature of ptarmigan
population dynamics can form the basis for citizen
science efforts in order to fill knowledge gaps for the
many regions that lack systematic ptarmigan monitoring
