Kolguev Island, north-west Russia in mid-July,
where it remained for about one month,
presumably to moult. Of two other individuals in
this study that undertook moult migration, one
went as far as the Taimyr Peninsula in Russia.
(Aarvak & Øien 2003).
Staging
Autumn migration is more protracted than spring
migration. Birds may remain at autumn staging
sites into early winter in mild seasons. Spring
migration typically appears to last from the second
half of February until the end of May, but there are
again significant annual variations related to
weather conditions.
Wintering
Satellite tracking and field observations suggest
that birds typically reach their wintering grounds
in the second half of November, remaining into
late February or the first half of March, according
to prevailing weather conditions.
shallow on the opposite bank giving way to wet
grassland and willow shrubs (Mineev & Mineev,
2004). In the Polar Urals and Yamal Peninsula
nests were located on rocky river cliffs and in
dwarf birch tundra on watershed slopes close to
rivers, and sometimes in mountain foothills. (V.
Morozov, pers. comm.)
In Siberia, nests are usually sited amongst
vegetation, grass or dwarf shrub heath, often on
snowfree patches available early in the season,
such as rock outcrop or prominent hummock;
often in proximity to open water or extensive
marshy area (Dementiev & Gladkov 1952,
reported by Fox 2005).
Moulting
In August 2000, a brief field survey was conducted
of the area of Kolguev Island, north-west Russia,
used in 1997 by a presumably moulting satellitetracked
goose of the Fennoscandian population.
The area was characterised by low-lying, flat
tundra, dissected by ponds and small river valleys
with slow-flowing streams. Vegetation was
dominated by shrub (dwarf birch Betula and
willows Salix) and tussock tundra with palsa mires
(Strøm et al. 2001). According to studies in the
Bolshezemelskaya tundra and Yamal Peninsula,
moulting areas occur on riverine areas with floodplain
meadows and dense bushes/shrubs
(Morozov, 1999).
