- Body Length (cm):
- The male (drake) of the Southern pochard measures approximately 48-50 centimeters. The female measures approximately 48-50 centimeters.
- Body Weight (grams):
- The male will weight about 455-815 gram. The female will weight about 455-815 gram.
The weight is notoriously variable and can only be used as indication!
There is two subspecies:
- Netta erythrophthalma brunnea - Southern(African) Pochard
- Netta erythrophthalma erythrophthalma - Southern(South America) Pochard
Nest is depression lined with grass, reed stems, down and some feathers, on ground or over water in thick vegetation.
- The female Southern pochard usually lays from 6-15 Creamy white eggs and incubates them for 26-28 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 26-28 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 Southern pochard is 11 mm.The leg band ring can only be applied on a young duck at around 12-14 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
