Subspecies:

Known subspecies:

  • Anas georgica georgica: South Georgia I.
  • Anas georgica niceforoi: Formerly Andes of Colombia. Extinct ca 1952
  • Anas georgica spinicauda: Highlands of s Colombia to Tierra del Fuego and Falkland Islands
Habitat:

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.

Note:

 

Dabbling Ducks are generally hardy, easy to maintain and easy to breed. Shelter may be required by some of the smaller species in winter. 

Yellow-billed pintails (Anas georgica spinicauda - Chilean pintail or Brown pintail) are winter-hardy and may be kept in a mixed collection with other ducks. These ducks (Anas georgica spinicauda - Chilean pintail) breed readily, using natural close ground cover for nesting, eggs laid April to May.

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. Hybrids reported with Wood duck (Aix sponsa), Red-crested pochard (Netta rufina) and various Anas species.

 

Breeding:
The female Yellow-billed pintail usually lays from 4-10 creamy or pale pinkish eggs and incubates them for 26 days.

Bird banding:
Recommended leg band size for the Yellow-billed pintail is 9 mm.
The leg band can only be applied on a young dabbling duck at around 12 days old.

It doesn't matter what leg that you band, but it is good to have a consistent system.
Suggested: Left leg = Female, Right leg = Male
