The blue duck is a very endangered species of duck. It is related to that of the duck, swan and goose families. They are native to New Zealand. The blue duck is also on New Zealand’s $10 note. They are one of New Zealand’s most endangered species of birds. Their population is severely dropping and there is only 3,000 left alive in the whole world. For both the mother and baby ducks even staying alive is a struggle. In the day time they swim in fast flowing waters so the parents have to always be near their chicks so that they don’t get swept away. As for the adults, predators like stoats for example, will use the cover of the night to help them hide, and then they will then put their ambush into action. The ducklings are also in danger at night too. If you want to help these birds without volunteering, you could help make a difference by picking litter up and putting them in your rubbish bin especially plastic bags, ( if you do this you can go to my Save the turtles page and email me how many plastic bags you have collected). One other threat to these awesome animals is one that is common to just about every exotic animal and that is: habitat destruction.
When the blue duck hatches out of it’s egg their bill is a green, but only for 8 hours, and then it will turn into its more yellow colour. The call of the male blue duck is kind of like a whistling sound. And the females call sounds more like a rattling growl. They will usually nest in hollowed out logs or caves along the riverbank. But because of this, they are vulnerable to floods.
They have a kind of soft lip on the tip of their beak witch works kind of like how your vacuume would work at home, this enables it to scrape off the little insects that live on the rocks in the water. Also the blue duck will mate for life and can have a territory of up to 1km of land/water. Their maori name is whio.
