Whio (Blue Duck) Single Sided Wooden Puzzle in Tray
Below information is printed on the back of the tray for your reference:
Whio are endemic to New Zealand so are found nowhere else in the world. Their name depicts the call of the male bird. Whio have unique features such as streamlined head and large webbed feet to enable them to feed in fast moving water. The upper bill has a thick semicircular, fleshy 'lip' that overlaps the lower bill allowing them to remove insect larvae off the rocks that they cling to , without wear and tear. The Whio is a river specialist which inhabits clean, fast flowing streams. They are an indicator of healthy rivers and streams. Whio are very camouflaged to evade predators. Adult length: 530mm; males are between 1000-1200gm; females between 800-1000gm. Whio moult between December and May. They are mainly active during early morning and late evening periods, hiding during the day – some populations have adopted an almost nocturnal existence. They are flightless during the moult period which makes them extremely vulnerable to predators. They are rarer than some species of Kiwi. Whio are one of only three species amongst the world's other 159 waterfowl that live year round on fast-flowing rivers. They get all their food (consisting almost exclusively of aquatic insect larvae) from the fast moving rapids and riffles.
