Transcript of The Haast Eagle

Made By Vaishalee, Nicola and JP Haast Eagle How & why has your species become extinct Early human settlers in New Zealand (the Māori arrived around the year 1280) preyed heavily on large flightless birds, including all moa species, eventually hunting them to extinction. The loss of its natural prey caused the Haast's Eagle to become extinct as well around the year 1400 when the last of its natural food sources were gone What did it eat? The Haast eagle used to eat; sheep, kiwi and humans, they were known to be feared in the lands. When they would try and eat the sheep the people would hunt them and kill them What was its habitat? Fossils have been found all across South Island, New Zealand. It shows that the areas where the Haast’s eagle lived were covered in forest and shrub lands, as well as in the grasslands on river floodplains.
Research by Dr. Richard Holdaway on the skeletal remains of the birds suggests that the New Zealand eagle was a forest eagle that could not soar but probably hunted like other forest eagles by perching high on a branch until a suitable prey came within range and then diving on it at speeds of up to 80 kilometres an hour. The impact, which could knock even the largest Moa off its feet, was cushioned by powerful legs.
With a life span approaching 20 years, the eagles occupied, in pairs, territories up to several hundred square kilometres. What adaptions did they have and what did they look like? What adaptations should they have had? If it is extinct, when did this happen? Most estimates place the female Haast Eagles10–15 kg and males around 9–12 kg. They had a short wingspan 2.6–3 m. The largest extant eagles, however, are about 40% smaller in body size than Haast's Eagles. Haast's Eagle adapted toward higher wing loading.Two of the largest extant eagles, the Harpy Eagle and the Philippine Eagle, also have similarly reduced relative wing-length in adaptation to forest-dwelling. Short wings may have aided Haast's Eagles when hunting in the dense scrub land. The strong legs and massive flight muscles of these eagles enabled the birds to take off with a jumping start from the ground. Total length is estimated to have been up to 1.4m in females. It's large beak also could be used to rip into the internal organs of its prey. It should have had another main food source other than the Moa. Is your species extinct yes and has been for a few hundred years The Haast eagle went extinct relatively recently. Evidence shows that this big eagle existed when the Maori first arrived in New Zealand around 800 years ago and some evidence may prove that the eagle may even have still existed when the Europeans arrived in the early 1800’s.
