The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 174 species in 43 genera.
The Oxyurini are a tribe of the duck subfamily of birds, the Anatinae. It has been subject of considerable debate about its validity and circumscription. Some taxonomic authorities place the group in its own subfamily, the Oxyurinae. Most of its members have long, stiff tail feathers which are erected when the bird is at rest, and relatively large, swollen bills. Though their relationships are still enigmatic, they appear to be closer to swans and true geese than to the typical ducks. The highest diversity is found in the warmer parts of the Americas, but at least one species occurs in a major part of the world.
The Anatinae are a subfamily of the family Anatidae. Its surviving members are the dabbling ducks, which feed mainly at the surface rather than by diving. The other members of the Anatinae are the extinct moa-nalo, a young but highly apomorphic lineage derived from the dabbling ducks.
The musk duck is a highly aquatic, stiff-tailed duck native to southern Australia. It is the only living member of the genus Biziura. An extinct relative, the New Zealand musk duck or de Lautour's duck, once occurred on New Zealand, but is only known from prehistoric subfossil bones. It was about 8% longer than the living species, with a particularly large head.
The Muscovy duck is a large duck native to the Americas. Small wild and feral breeding populations have established themselves in the United States, particularly in Florida, Louisiana, Massachusetts, the Big Island of Hawaii, as well as in many other parts of North America, including southern Canada. Feral Muscovy ducks are found in New Zealand, Australia, and in parts of Europe.
Elon Reeve Musk is an entrepreneur and business magnate. He is the founder, CEO and Chief Engineer at SpaceX; early-stage investor, CEO and Product Architect of Tesla, Inc.; founder of The Boring Company; and co-founder of Neuralink and OpenAI. With an estimated net worth of around US$304 billion as of January 2022, Musk is the wealthiest person in the world.
The blue duck or whio is a member of the duck, goose and swan family Anatidae endemic to New Zealand. It is the only member of the genus Hymenolaimus. Its exact taxonomic status is still unresolved, but it appears to be most closely related to the tribe Anatini, the dabbling ducks.
The Canterbury Museum is a museum located in the central city of Christchurch, New Zealand, in the city's Cultural Precinct. The museum was established in 1867 with Julius von Haast – whose collection formed its core – as its first director. The building is registered as a "Historic Place – Category I " by Heritage New Zealand.
Hawkins' rail or the giant Chatham Island rail is an extinct species of flightless rail. It was endemic to the Chatham Islands east of New Zealand. It is known to have existed only on the main islands of Chatham Island and Pitt Island. Hawkins's rail was the largest terrestrial bird native to the Chatham Islands, around 40 centimetres (16 in) tall and weighing about 2 kilograms (4.4 lb). It had a long, downward curving beak. Historic accounts likely referring to the bird by the name Mehonui suggest that it was red-brown in colour, and it has been compared to the weka in ecological habits, using its beak to probe decaying wood for invertebrates. Hawkins's rail likely became extinct due to overhunting by the islands native inhabitants, the Moriori, and the bird is known from skeletal remains found in their kitchen middens.
Finsch's duck was a large terrestrial species of duck formerly endemic to New Zealand. The species was possibly once the most common duck in New Zealand, a supposition based on the frequency of its fossils in bone deposits. The species was originally considered to be in its own genus, Euryanas, but is now known to be closely related to the maned duck and recently derived from that species.
Lake Poukawa is a small shallow hardwater lake in the Hawke's Bay Region, North Island, New Zealand. It is located about 20 km south-west of Hastings, New Zealand, close to the settlement of Te Hauke. It is the largest lake lying within a peatland in the active tectonic Poukawa depression, between the Raukawa Range and Kaokaoroa Range of central Hawke's Bay. Its maximal depth is less than one metre and its diameter is ca. 1.5 km. It was deeper in the past but it was artificially drained after the 1931 Hawke's Bay earthquake. Lake Poukawa became a well-known paleontological site in 1956 when paleontologist Russell Price began with his excavations in the lacustrine deposits. Lake Poukawa had a species rich Pleistocene/Holocene waterfowl fauna. More than 13,400 anatid bones were unearthed at this site since 1956. Extinct birds found at Lake Poukawa include Biziura delautouri, Oxyura vantetsi, Mergus australis, Chenonetta finschi, Pachyornis geranoides, Ixobrychus novaezelandiae, Gallinula hodgenorum, Fulica prisca, Malacorhynchus scarletti, and Cnemiornis gracilis.
Lake Warden is a salt lake in the Goldfields-Esperance region of Western Australia. It and its associated wetlands are protected in a nature reserve; they were recognised as being of international importance under the Ramsar Convention through designation of the Lake Warden System on 7 June 1990 as Ramsar Site 485. The lake is also a DIWA-listed wetland.
The New Zealand musk duck, also known as de Lautour's duck, is an extinct stiff-tailed duck native to New Zealand. It is only known from subfossil bones. Its closest relative was the living Australian musk duck Biziura lobata, with which it has sometimes been combined.
Tosca Musk is a South African filmmaker. She is an executive producer, producer, and director of feature films, television programs, and web content. Her work includes K. Bromberg's Driven, Rachel van Dyken's Matchmaker's Playbook, and her web series, Tiki Bar TV. Tosca is the sister of entrepreneurs Elon Musk and Kimbal Musk and daughter of Maye Musk. She co-founded the streaming service Passionflix.
The Chatham coot, also known as the Chatham Island coot, is an extinct bird in the rail family, Rallidae, that was endemic to the Chatham Islands of New Zealand. It was described from subfossil bones in 1892 by Scottish explorer, ornithologist and botanist Henry Forbes, who was director of the Canterbury Museum in Christchurch at the time.
