Aviculture Information

Notes

General information:
  • Perching Ducks and "geese" are generally happier maintained fully-flighted if possible, for example in an aviary for the smaller species, or under flight netting.
  • While the larger species in this group are hardy, the smaller species may be more delicate and require winter shelter. These species eat a high proportion of vegetable matter and appreciate a grazing area. Most of these species are hole-nesters.
  • Many of these species are sociable outside the breeding season, although Cairina moschata - Muscovy duck, Cairina scutulata - White-winged duck, Pteronetta hartlaubii - Hartlaub's duck and Plectropterus gambensis - Spur-winged goose can all be aggressive and require separate enclosures.

(B7, B11.33.w1, B94, D1)

Species-specific information:

  • Ringed teal are reasonably winter-hardy, but shelter should be provided for frosty weather. They are suitable for mixed collections, but are quiet and may be bullied. They are easy to house and feed: grain, pellets, grass, greenfood and bread, with some animal-matter appreciated. They like to perch over water.
  • Easy to breed, breeding of these ducks is better if they are left fully-flighted, e.g. in an aviary, with a tree hole or raised nesting boxes provided. Laying usually from May, but may start in March - delayed if cold weather (B31);  mainly April to June (B29); May-July (B108,). Reliable incubator if not disturbed, and may be safely parent reared (both parents tend); may also be hand-reared. Pairs kept isolated fully flighted in a covered pen, with high-hung nest boxes "seldom fail to rear broods" (B7). Good rearing meal supplemented by live insects and fine-chopped green food suggested for rearing ducklings.
  • Rarely hybridise, but hybridisation hybridisation with Amazonetta brasiliensis - Brazilian teal: offspring were sterile.

(B7, B29, B31, B94, B96, B97, B108, D1).

Aviornis UK Ringing Scheme recommended average ring size: H 8.0mm (D8).
