Many thanks to Colin Hill for giving answers to our questions.
About 600 birds are killed each year by hunters.
Pukekos like to live in very muddy swamps.
Pukekos are considered as pests and so people are allowed to shoot them.
People are getting worried about the population getting lower and lower.
Chicks are looked after by both parents.
The black swan population was about 60,000 birds before the Wahine storm and hunters were encouraged to shoot them. After the Wahine storm the numbers were reduced. Farmers think they are a pest because they eat the crops.
One black swan eats as much as two adult sheep.
Black swans lay 6-8 eggs. They build their nests from rushes, leaves, grass and straw near the edge of the water.
Black swans strip grass and eat their roots.
