"The Bush Supermarket" by Julie Stroud inspired us to analyse how native birds interact with our native bush.
All ecosystems, whether they are marine, freshwater or located in native bush, involve relationships between plants and animals. In our native bush there is an important relationship between birds and our plants and trees.
Fantail - GOTG
The fantail or piwakawaka eats flying insects, caterpillars and spiders low down among the ferns and tree ferns in the bush. The fantail is able to eat these insects as they use their upright tails for hovering and have bristles around their beak which act like a net. If the fantail was to be removed from the bush ecosystem the number of insects would multiply. Pest insects would spread disease and damage crops meaning fewer native plants and trees.
Wood Pigeon - GOTG
Many of our native trees depends on the wood pigeon or kereru to eat their fruit and spread seeds. The bird’s loss would be a disaster for our bush. Native plants are dependent on birds for successful seed dispersal and regeneration. Once a seed has passed through the digestive tract of a bird, it will often be dropped far away from the host tree’s location, enabling the tree to potentially colonise a new area. Without the kereru native trees would not grow as widely. Trees are needed for oxygen, shelter and to control the temperature and without them our world would not be the same
Harrier Hawk - X-Men
The Harrier hawk has a vital role in the bush environment as it cleans up the leftovers of dead animal carcusses. By doing that role the bacteria from carcusses will not spread disease across the forest. The Harrier Hawk also controls pests such as rats and mice. Without the hawk controlling numbers the rats, mice and rabbits would destroy seedlings and spread disease.
Kingfisher - Avengers
The kingfisher or kotare eats small fish called minnows, shrimps, crayfish and frogs. If the kingfisher was removed from the bush ecosystem the food chain would collapse. There would be an overpopulation of fish, frogs and crayfish. This would mean there would be more competition for food sources meaning more animals would die.
New Zealand native birds have a key role in the pollination and seed dispersal of our native flora as well as protecting the bush from predators. Birds are essential to ensure the future of our native bush ecosystem for generations to come. Therefore it is important to protect them from harm by conserving our native bush.
