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:

  • Cape shovelers are sociable and suitable for mixed collections. They should be maintained in an enclosure with good bankside vegetation and fairly shallow muddy water. Feed as other ducks: grain, pellets, bread, greenfood.
  • These ducks have been bred fairly regularly. Close ground cover and ground-level nest boxes should be provided. Ducklings are very insectivorous and require live food.
  • Hybridisation reported with Anas platalea - Red shoveler.

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

Aviornis UK Ringing Scheme recommended average ring size: K 10.0mm (D8).
