BEHAVIOURAL
Blue ducks feed on aquatic insects, mostly at dawn and dusk. They stay the rest of the day in a sheltered
place. Pairs of blue ducks form a long-term breeding relationship. The breeding
seasons start in July and go on as late as December. Each pair protects their
breeding territory and they place their nest in a stream-bank under a log, rock
or clump they lay 4~9eggs which are incubated by the female for 31~32
days

PHYSIOLOGYCAL
Blue ducks have large webbed feet to enable them to feed in fast moving water and
helps them dive for food between large rocks.
They have a thick semi-circular fleshy lip that overlaps the lower bill allowing them to scrape
off insects that cling to rocks so they don’t hurt themselves. When they hatch
70-days later chicks can fly. Adult blue ducks are 53mm and males weigh 100g,
females 800g.

Why adaptations are important?
These adaptations are important because we can identify blue ducks.
We will be able to tell the difference from other birds.
It will be easy to find out how we protect blue ducks from other predators
