Aviculture Information

Notes

General Information:
  • Dabbling Ducks are generally hardy, easy to maintain and easy to breed. Shelter may be required by some of the smaller species in winter. They should be provided with cover (including marginal pond cover) and loafing areas as well as water. A pen which is 50% water is suggested. The water may be shallow (i.e. no more than two feet deep is required), and muddy areas for dabbling in are also appreciated. These ducks are generally good in mixed collections, although the smaller and quieter species may be bullied. Territorial disputes between ducks of the same species may be avoided by keeping only one pair of each species in an enclosure, unless the area is very large. For a single pair of ducks a pen are of 50 to 100 square metres, depending on the size of duck, should be provided.
  • A diet based on wheat and pellets is suggested, with maintenance pellets changed to breeders pellets for the breeding season. Bread and greenfood are also appreciated. Grit should always be available, with soluble grit (e.g. oystershell grit) as a calcium source when breeding.
  • Most species are ground nesters and both close ground cover and ground level nest boxes should be provided. Hand-rearing is generally preferred, as these ducks are generally poor parents in captive conditions, particularly in enclosures shared with other waterfowl. These ducks are prone to hybridization, particularly with closely related species, which should be kept apart from one another.

(B7, B29, B30, B40, B94, B128.w1, D1)

Species-specific information:

  • White-cheeked pintail (Bahama pintail) are winter-hardy, but shelter should be provided if the water is totally frozen. Non-aggressive, easy to keep and breed, these ducks may be kept in mixed collections. Feed with grain and pellets, plus bread and green food.
  • These ducks will use ground-level nest boxes or nest on the ground under vegetation, preferring secluded areas such as under thick bushes or in hollows at the base of trees. Laying usually from May, sometimes April. They are reliable for parent incubation and rearing, but will lay a second clutch if the first is removed. They may desert their eggs if frequently disturbed.
  • Hybridisation not common, particularly if firmly paired, but has been reported with Anas georgica - Yellow-billed pintail (Anas georgica spinicauda - Chilean pintail), (Anas georgica spinicauda - Chilean pintail), Anas flavirostris - Speckled teal, , Amazonetta brasiliensis - Brazilian teal, Aix sponsa - Wood duck and other Anas spp.
