Typically found in a lake at a mean distance from sea level of 343 meters (1,126 feet).
Behaviour This species is fully migratory and travels on a narrow
front2 between extremely localised
areas1. It is present on its breeding
from May or June to August or September2
where it breeds
in small but often closely packed colonies1,
3 of 5-50 pairs, occasionally singly or in groups of up
to 150 pairs6. It uses the same nesting sites year
after year4 and sometimes nests
among seabird colonies3.
After the young hatch
undergo a flightless moult period
near the breeding grounds
between mid-July and mid-August that lasts
for 3-4 weeks5. The species migrates to autumn
areas in September2 from which it travels
via regular stop-over sites3 to the wintering grounds,
arriving in late-September2. The return migration
begins in April or May, the species moving to spring
where it may be present for 20-30 days before migrating
The species is highly gregarious
outside of the breeding season
often feeding in dense concentrations on coastal grasslands during
the winter3. In winter habitats
it roosts on water3
or on sandbanks near saltmarshes and pastureland10.
Habitat Breeding The species breeds in Arctic
(fjellmark)2 on crags, rocky outcrops1,
, rocky slopes4 and coastal islands (Svalbard)2
near wetlands such as lakes
, marshes, the upper parts of
, coastlines4, wet meadows and mudflats2.
In years when the snow is slow to melt the species first forages
on grassy vegetation on south-facing mountain slopes
the droppings of cliff-nesting seabirds before moving down
areas2. It also returns to these slopes after the
moulting period before autumn migration2. After
the young hatch families may disperse away from rocky ground to more
vegetated areas surrounding tundra lakes and rivers2.
Non-breeding During the non-breeding season
the species frequents
, saltmarshes2, 4 and adjacent
meadows1, 4 (especially improvedrough pasturesand
arable land1, 2), with agricultural fields
increasingly more important as winter feeding areas5.
The species is herbivorous1 its diet
consisting of the leaves, stems and seed-heads of grasses, sedges,
plants1, 2, mosses2,
various herbs (especially white clover Trifolium repens in
the winter)8, 10 and shrubs
Salix arctica)4. It may also take agricultural
grain and vegetables during the winter1. Breeding
site The nest is a shallow depression
in a low mound of vegetation6
positioned on rocky ground1, 2, rocky outcrops4,
6, among rocky crags, on steep cliffs3, 4, 6,
on the tops of low hills4, or on low vegetation
hummocks and snow-free patches on islands in river channels6.
Nesting sites accumulate nesting materials
as they are often used
year after year4, and the species may sometimes
nest among seabird colonies3. Management
An investigation carried out in one of the species's wintering
areas (UK) found that it was most likely to forage on improved grasslands
with high abundances
of the grass
Lolium perenne and white
clover Trifolium repens8 (the growth of
which is greatly influenced by the amount of summer grazing, which
the grass height)10. Preferred fields
were between 4 and 10 ha in area (the species avoided fields of less
than 2-3 ha), and at an optimal distance
of less than 5 km
roosting sites (maximum 7 km away)8. The species
was also found to show a preference for grasslands with swards less
than 10 cm in height
(optimum 2 cm) in fields that had been cut
and then grazed (although there was no major difference in
on pastures grazed with different livestock)8.
Overall winter use of grassland fertilised with large amounts of
nitrogen was significantly greater than the use of unfertilised grassland
by the species8. The Barnacle Goose Management
Scheme (BGMS) in Scotland, UK recommends fertilising farmland adjacent
to reserves containing wintering groups of this species at times
when geese are present (e.g. autumn or winter) and grazing stock
(sheep or cattle) are absent9. The BGMS also awards
payments to farmers who manage pastures outside of established
for reducing the level of disturbance
(e.g. scaring away feeding
flocks) on their land9.
