Description
- Description:
Male:
Is almost all grey-brown. Each feather of the body is edged with buff, except on the rump. The chin and throat are white, the bill is dark green and the eye is red. The secondary wing feathers have glossy blue-black patch, broadly bordered and tipped with white. In flight, a large white wedge is visible on the underwing.Female:
Identical to male , But smaller and less iridescent in speculum. calls are different as well.Juvenile:
As female, But less mottling and lighter brown tell 2nd winter males show more iridescents on speculum through first wet season.
Standard Measurements
- Body Length (cm):
- The male (drake) of the Australian grey teal measures approximately 37-47 centimeters. The female measures approximately 37-47 centimeters.
- Body Weight (grams):
- The male will weight about 680 gram. The female will weight about 590 gram.
The weight is notoriously variable and can only be used as indication!
- Subspecies:
- a.g. gracilis: from New Guinea to Australia, New Caledonia and New Zealand.
- a.g. remissa: Solomon Islands (possibly extinct).
- Habitat:
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. 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.
Grey teal may be kept in mixed collection with other ducks in a large area, or maintained in a separate pen. These ducks breed quite readily; natural close ground cover, hollow log, ground-level box or a raised box may be used for nesting.
Hybridisation with Chestnut teal (Anas castanea) or Australian wood duck (Chenonetta jubata) is likely if they are kept in the same pen.
- Breeding:
- The female Australian grey teal usually lays from 6-14 Creamy white eggs and incubates them for 28 days.
- Artificial incubating:
The ideal relative humidity for incubating most waterfowl eggs is 55% (ground nesters) and 40% (cavity nesters). The temperature is usually 37.4°C. Set ventilation as recommended by the incubator manufacturer. Eggs must be turned, either automatically or by hand, a minimum of 4 times a day. As the duckling develops there is a loss of water from the egg and the air sac gets bigger. In normal development of an egg with a 28 days incubation, the air sac occupies about a third of it three days earlier. Cleanliness is vital and ideally eggs should be moved to a separate hatcher at this point, where the humidity should be increased to 65% and even higher once they have pipped internally.
- Bird banding:
- Recommended closed leg band ring size for the Australian grey teal is 9 mm.The leg band ring can only be applied on a young dabbling duck at around 11-12 days old.
- It doesn't matter what leg that you band, but it's good to have a consistent system. Suggested: Left leg = Female, Right leg = Male
