A cockatoo is any of the 21 bird species belonging to the family Cacatuidae. Along with the Psittacidae family (the true parrots) and the Nestoridae family, they make up the order Psittaciformes. The name cockatoo originated from the Malay name for these birds, kaka(k)tua (either from kaka "parrot" + tuwah, or "older sister" from kakak "sister" + tua, "old"). Placement of the cockatoos as a separate family is fairly undisputed, but it is not resolved whether or not other living lineages of parrots (such as the lories and lorikeets) are as distinct as they appear. The family has an Australasian distribution, ranging from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia.
Cockatoos are, on average, larger than true parrots; however, the Cockatiel, the smallest cockatoo, is a small bird, while some of the largest parrots, including the Hyacinth Macaw (the longest parrot) and the flightless Kakapo (the heaviest parrot), are true parrots. Their plumage is generally less colourful than that of the other parrots, being mainly white, grey or black with some colour elsewhere. Like other parrots they have strong bills and feet.
The diet of the cockatoos is composed of seeds, tubers, corms, fruit, flowers and insects. They often feed in large flocks, particularly if they feed on the ground. Cockatoos are monogamous and nest in tree hollows.
Cockatoos are popular birds in aviculture; although, for some species, the largely illegal trade in wild-caught parrots has threatened their survival. Some cockatoo species are threatened by habitat loss and particularly by the loss of suitable hollows for nesting as large, mature trees are cleared; conversely, some species have adapted well to human changes and are considered agricultural pests.

Shoebill

Shoebill, Balaeniceps rex, also known as Whalehead, is a very large stork-like bird. It derives its name from its massive shoe-shaped bill. The Shoebill is a very large bird. The adult is 115-150 cm (45-59 in) tall, 100-140 cm (40-55 in) long, 230-260 cm (91-103 in) across the wings and weighs 4 to 7 kg (8.8-15.5 lbs). The adult is mainly grey while the juveniles are browner. It lives in tropical east Africa in large swamps from Sudan to Zambia.
This species was only discovered in the 19th century when some skins were brought to Europe. It was not until years later that live specimens reached the scientific community. However, the bird was known to both ancient Egyptians and Arabs. There are Egyptian images depicting the Shoebill, while the Arabs referred to the bird as abu markub, which means one with a shoe, a reference to the bird's distinctive bill.
Shoebills feed in muddy waters, preying on lungfish and similar fish, as well as frogs, turtles,carrion, and even baby crocodiles. They nest on the ground and lay 2 eggs.
The population is estimated at between 5,000 and 8,000 individuals, the majority of which live in Sudan. BirdLife International have classified it as Vulnerable with the main threats being habitat destruction, disturbance and hunting.
The Shoebill is one of the bird taxa whose taxonomic treatment is murky. Traditionally allied with the storks (Ciconiiformes), it was retained there in the Sibley-Ahlquist taxonomy which lumped a massive number of unrelated taxa into their "Ciconiiformes". More recently, the shoebill has been considered to be closer to the pelicans (based on anatomical comparisons; Mayr, 2003) or the herons (based on biochemical evidence; Hagey et al., 2002). A recent DNA study suggests they're part of the Pelecaniformes.[4] The fossil record does not shed much light on the issue, as usual when dealing with birds. So far, two fossil relatives of the shoebill have been described: Goliathia from the early Oligocene of Egypt and Paludavis from the Early Miocene of the same country. It has been suggested that the enigmatic African fossil bird Eremopezus was a relative too, but the evidence for that is very spurious indeed. All that is known of Eremopezus is that it was a very large, probably flightless bird with a flexible foot, allowing it to handle either vegetation or prey.
