Aviculture information

Notes

• Sheldgeese are generally hardy, and mostly aggressive particularly in the breeding season, so that pairs require a separate pen. A pen for a pair of these birds may be 80% grazing land to 20% water, with a minimum size of 200 square metres for the smaller species (e.g. Orinoco goose) and 300 square metres for the larger species.
• Grazing birds, their grass (sward of less than 3 inches 7.5cm preferred) should be supplemented with wheat and pellets outside the breeding season and breeders pellets before and during the breeding season. Additional green food should be provided when there is insufficient grass.
• Sheltered nest sites may be needed for species which nest early in the year. Ground-level nest boxes, open to the ground, 20x16x16 inches (50x40x40cm), with a ground level entrance hole and containing e.g. dry grass as nesting material.

(B7, B29, B40, B95, B128.w1, D1)

Species-specific information:

• Kelp geese have been kept in collections very rarely, and bred very rarely, but at least once. Their specialised feeding habits make captive management problematic. Provision of open vegetation and a box or other shelter as a nesting site is suggested.

(B29, B30, B94, B97, B128.w2).

Aviornis UK Ringing Scheme recommended average closed ring size: P 14.0mm, perhaps R 16.0mm, and for males of Chloephaga hybrida malvinarum S 18.0mm (D8).
