Standard Measurements

Body Length (cm):
The male (drake) of the Australian Shelduck measures approximately 59-72 centimeters. The female measures approximately 56-68 centimeters.
Body Weight (grams):
The male will weight about 1300-1600 gram. The female will weight about 1300-1600 gram.
The weight is notoriously variable and can only be used as indication!
Note:

Between May and October, the eggs are laid in a tree or sandbank hollow. Eggs may also occasionally be laid on the ground, in hollow stumps, in limestone caves or on cliff ledges. The birds often return to the same nesting site. During this time, the male defends a separate territory, where the young will be reared, which may be some distance from the nest site. When the ducklings are about two days old, they are led to this territory by their parents.

Breeding:
The female Australian Shelduck usually lays from 8-14 Creamy white eggs and incubates them for 30-33 days.

Bird banding:
Recommended leg band size for the Australian Shelduck is 14 mm.
The leg band can only be applied on a young shelduck at around 12-14 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
