Resource partitioning in sympatric arctic‐breeding geese: summer habitat use, spatial and dietary overlap of Barnacle and Pink‐footed Geese in Svalbard

Abstract: The spatial, habitat and dietary overlap of two breeding goose species was studied in Sassendalen, Svalbard, in summer 2003 based on abundance within 500 × 500‐m grid squares and faecal diet analyses during pre‐breeding, nesting and post‐hatching periods. More than half of all Pink‐footed Geese Anser brachyrhynchus occurred in the absence of Barnacle Geese Branta leucopsis during nesting and post‐hatching periods compared to c. 20% when concentrated by pre‐breeding snow cover. In contrast, only 5% of Barnacle … Show more

“…The present distribution seems to be limited by the length of the frost-free period during summer (Jensen et al 2008). After hatching, families feed in lowland marshes and moss fens, under bird cliffs, and often move far inland, away from open water (Jepsen et al 2002;Fox et al 2007;Fox et al 2009;Madsen unpubl. data).…”

“…In contrast, pink‐footed geese often feed far inland, and will not seek protection on lakes; instead, they run inland, towards the river (in Sassendalen; Fox et al. 2007; Fox et al. 2009) or retreat to the sea.…”

“…Most of these populations have increased significantly over the last few decades due to conservation efforts, intensified agricultural practices and a warmer climate (Abraham et al 2005;Fox et al 2005;Kery et al 2006;Bauer et al 2008;Fox et al 2010). The Arctic tundra is therefore linked to European land use and conservation policies and management strategies for migrating goose populations.…”
