Interesting reading on that question over at wikipedia. The Kakapo of New Zealand. Also, known as the owl parrot.

Penguins use their lungs to breath.

Māori settlers from Polynesia hunted the Kakapo for food and for their skins and feathers, which were made into luxurious capes.[47] They used the dried heads as ear ornaments. Due to its flightlessness, strong scent and habit of freezing when threatened, the Kakapo were easy prey for the Māori and their dogs. Their eggs and chicks were also predated by the Polynesian Rat or kiore, which the Māori brought to New Zealand

Both the Greater Roadrunner (famous from the looney tunes cartons) and Ostrich are fast birds on land. The Greater Roadrunner can run at speeds of up to 20 miles per hour (32 km/h) which is fast for its size (56 centimeters 22 in long). The Ostrich on the other hand can run at speeds of up to 45 miles per hour (72 km/h) and is 1.8 to 2.75 meters (6 to 9 ft) above the ground which is considerably bigger than the Roadrunner. The Ostrich is also the fastest running bird.

The takahe is a large, flightless bird belonging to the rail family. It is endemic to New Zealand and was thought to be extinct but was rediscovered by Geoffrey Orbell in the Murchinson mountains in 1948.

fastest flapping flight. white-throated needle-tailed swift at 170 km/h (106 mph)

The fastest diving bird (not flapping) is the Peregrine Falcon

I believe your wrong. It's the Hummingbird.

Being a flightless parrot, the kakapo finds its food on the ground or by climbing trees. Their feet are designed as all parrots' feet are - with two sharp claws facing forwards and two facing backwards, which enables it to climb trees, even though it cannot fly. It is often a ground feeder, finding fruits, seeds, roots, stems, leaves, nectar and fungi. Kakapo eat certain fruits such as that of the rimu and kahikatea and the seeds of manuka and leatherwood. They eat the shoots of the shrub Dracophyllum. In the warmer months they drink rata nectar, while in winter they feed on sun orchid bulbs.

Penguins live in the Arctic region.With 17 different species, The emperor penguins stay on land during most of the seasons. With each different season change they endure crucial weather and a threat to their place of living due to climate change.In the Summer they travel to their breeding grounds so they can reproduce. The female only will produce up to one egg at a time.The male then takes over protection of this young egg.. And the mother then goes to the water and retrieves food for the young when hatched.

Kakapo lay between one and four eggs each breeding season, which only occurs every 2-3 years. The average is two eggs.

There has not been enough research done into the lifespan of the kakapo, as so few of these birds are left, and the remaining specimens must be kept in secure, protected areas. The lifespan is believed to be around 90 years, but there is no definitive figure available.

The American Coot is a type of duck. The body is a dark gray and the head/neck is black. They stay in the water most of the time.

Well according to this animal guy on T.V. it is the Double-Wattled Cassowary (http://nationalzoo.si.edu/Animals/Birds/Facts/FactSheets/fact-cassowary.cfm) . Also this person seems to agree http://www.pbase.com/image/70822934. I have not really seen any hard evidence of this but it was pointed out that it may be related to the famous Velociraptor.

Hard evidence for this is the fact that it is the only bird that has intentionally killed a human, there is more than one case of death.

Kakapo used to be found throughout New Zealand, but as of 2014, they are restricted to just three islands, not two. They are now found only on Anchor Island, Codfish Island (Whenua Hou) and Little Barrier Island (Hauturu).

A substantial population used to live on Stewart Island, but these kakapo were wiped out by the feral cats there.

The average weight of a crane bird can be between 8.8 and 26.5 pounds. They may grow between 3 and 7 feet in length and live between 20 and 30 years.

There is no bird similar to an ostrich in Australia. The tallest bird is the emu and, although it is a ratite (one of a particular group of flightless birds) like the ostrich, it is very different in appearance and behaviour.

Female kakapo weigh between 1.5 and 2 kg. Being flightless, kakapo are the world's heaviest parrot.

The fastest bird on earth is the Peregrine Falcon, which in a dive can reach speeds of approximately 180mph. And it is the fastest animal ever to walk this Earth!

Ducks are not flightless. In some places, ducks are migratory birds, flying long distances in winter.

The Ostrich is the largest flightless bird in the world. Its height ranges from around 2 m to 2.8 m, or 6'11" to 9'2" for males, which are larger than females.
