Standard Measurements
- Body Length (cm):
- The male (drake) of the Blue-winged Goose measures approximately 65-75 centimeters. The female measures approximately 65-75 centimeters.
- Body Weight (grams):
- The male will weight about 1800-2200 gram. The female will weight about 1520 gram.
The weight is notoriously variable and can only be used as indication!
- Note:
During the mating season the male blue-winged goose struts his stuff with his head bent over his back exposing his blue wing patch for her to inspect. The courtship and breeding takes place by lakes and streams in the mountains and they build their nests in among grass tussocks.
- Breeding:
- The female Blue-winged Goose usually lays from 4-7 creamy white eggs and incubates them for 30-32 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 30-32 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 Blue-winged Goose is 14 mm.The leg band ring can only be applied on a young goose 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
