“…A markrecapture study of rock ptarmigan in Greenland proved migration up to 1000 km from north to south (Salomonsen 1950), but to what extent ptarmigan move over open sea is not clear. However, willow ptarmigan Lagopus lagopus have been observed 17 km from the nearest coastline flying, and also landing and taking off from the water (Zimmerman et al 2005). Grit analyses have also verified that the northeast Greenland rock ptarmigan Lagopus m. captus occasionally occurs in Iceland (Gudmundsson 1972) implying that long distance migrations over the sea (shortest distance is 300 km) happens.…”

“…Rare overwater movements have been observed in arctic ptarmigan (Lagopus spp.) [22] (but see [23,24]), otherwise historical movements of phasianoid lineages between North America and Asia were likely to have been facilitated by the Bering Land Bridge [25].…”

How do seemingly non-vagile clades accomplish trans-marine dispersal? Trait and dispersal evolution in the landfowl (Aves: Galliformes)

Dispersal ability is a key factor in determining insular distributions and island community composition, yet non-vagile terrestrial organisms widely occur on oceanic islands. The landfowl (pheasants, partridges, grouse, turkeys, quails and relatives) are generally poor dispersers, but the Old World quail (Coturnix) are a notable exception. These birds evolved small body sizes and high-aspectratio wing shapes, and hence are capable of trans-continental migrations and trans-oceanic colonization. Two monotypic partridge genera, Margaroperdix of Madagascar and Anurophasis of alpine New Guinea, may represent additional examples of trans-marine dispersal in landfowl, but their body size and wing shape are typical of poorly dispersive continental species. Here, we estimate historical relationships of quail and their relatives using phylogenomics, and infer body size and wing shape evolution in relation to trans-marine dispersal events. Our results show that Margaroperdix and Anurophasis are nested within the Coturnix quail, and are each 'island giants' that independently evolved from dispersive, Coturnix-like ancestral populations that colonized and were subsequently isolated on Madagascar and New Guinea. This evolutionary cycle of gain and loss of dispersal ability, coupled with extinction of dispersive taxa, can result in the false appearance that non-vagile taxa somehow underwent rare oceanic dispersal.

Dispersal distances of juvenile radiotagged Red Grouse Lagopus lagopus scoticus on moors in northern England

Radio‐transmitters were fitted on 146 juvenile Red Grouse Lagopus lagopus scoticus (116 hens, 30 cocks) to study the timing, frequency and distances of dispersal on managed grouse moors in northern England between 1999 and 2002. A third of the radiotagged birds were shot. Disturbance on shoot days meant that radiotagged birds were shot at points more than twice as far from the catch location as the points when they were last recorded alive. For birds that were shot, the distance from the catch location to the place they were shot was more than twice the natal dispersal distances of the survivors. Therefore, shot birds were excluded from the dispersal analysis. Juvenile hens dispersed significantly further (mean 861 m, range 50–4660 m) than juvenile cocks (mean 343 m, range 90–660 m). Dispersal distances were not related to predispersal Grouse densities at the catch area in summer or to Grouse densities in the following spring. The mean date of dispersal for juvenile hens was 6 October ± 4 days (se), with only one record of spring dispersal (14 March) of 1490 m.
