A photo of a threatened species. Most of the time you see photos of the Southern Cassowary. Taken in Welt Vogelpark Walsrode in Germany.

The Northern Cassowary, Casuarius unappendiculatus, also known as the Single (One)-wattled Cassowary or Gold(en)-neck(ed) Cassowary, is a large, stocky flightless bird.

Taxonomy
It's binomial name Casuarius unappendiculatus, can be broken down to Casuarius is kesuari Malay for cassowary. unappendiculatus means unus, one, appendicis, appendage, -culus, diminutive, and -atus, provided with: cassowary provided with one small appendage, referring to the single wattle. Officially, there are no sub-species, however, some authors list several sub-species.

Description
It has hard and stiff black plumage, blue facial skin and a casque on top of the head. It has a bright red or yellow colored neck and wattle. The feet are huge and strong with long, dagger-like claw on its inner toe. The sexes are similar. The male, at 37 kilograms (82 lb), is smaller than female, at 58 kilograms (130 lb). These birds are between 165–175 cm (65–69 in) in height.

Phylogeny
Casuariidae is the family of the Northern Cassowary. There are only four members of this family, three of them are Cassowary’s, and the other member is the only remaining species of Emu. As you can probably guess from the above information, all four species of bird are quite similar. Emu’s were formerly classified in a different family, until it was decided that they are alike enough to the Cassowary’s that they could be classified in the same family. All four members of the Casuariidae family are large and also flightless birds. The Northern Cassowary shares an analogous feature with the Aptenodytes forsteri, also known as The Emperor Penguin. The Northern Cassowary and the Emperor Penguin are indeed from separate families, though both of them possess wings, but incidentally cannot fly. The structure is the same; a forearm and finger-like bones that are covered by their wing.

Although the two species are incredibly dissimilar, this similarity between them serves the same function. The Northern Cassowary and the Emu share homologous features. For example, both the Northern Cassowary and the Emu have a blue patch of colour on their face/neck, but the functions of these differ. The Emu’s patch of fur is of a paler colour, and is used as a form of camouflage where it is located. The Northern Cassowary’s patch of blue is brighter, and is used for attracting mates.

Range and habitat
The Northern Cassowary is distributed and endemic to coastal swamp and lowland rainforests of northern New Guinea and the islands of Yapen, Batanta and Salawati. They prefer elevations below 490 m (1,610 ft).

Behavior
As with other cassowaries, it is a shy and solitary bird. Their diet consists mainly of fruits and small animals. They make grunting and hissing sounds, like other cassowaries.

In breeding season, the polygamous female lays three to five green eggs on a well camouflaged nest prepared by male, she leaves the nest and eggs to find another mate. The male raises the chicks alone for about nine months.

Conservation
Due to ongoing habitat lost and overhunting in some areas, the Northern Cassowary is evaluated as Vulnerable on the IUCN Red List of Threatened Species, with hunting being the biggest threat. Native people use the bones and eggs, and take the chicks to be raised for meat. As logging opens up more areas of the forest, hunting will be more of a problem. Their occurrence range is 186,000 km2 (72,000 sq mi) and a 2000 estimate placed their numbers at 9300.

Hello Peter,
Walsrode is really rich in all sorts of very exotic birds..this Cassowary is a good example for it. Excellent idea to show its very striking-colored head and this amazing casque. Its golden eye is also impressive. The bush-background is a little bit noisy, but you had probably no other possibiliy.
Have a nice weekend
Anne
