The New Caledonian barn owl (Tyto letocarti), also referred to as Letocart's barn owl, is an extinct species of owl in the barn owl family. It was endemic to the island of New Caledonia in Melanesia in the southwestern Pacific region. It was described from Late Pleistocene to Holocene aged subfossil bones found at the Gilles Cave paleontological site on the west coast of Grande Terre. The holotype is a complete adult left femur (NCG 1000), held by the Muséum national d'histoire naturelle in Paris. The owl was described as Tyto? letocarti, indicating uncertainty as to generic placement at the time. The specific epithet honours Yves Letocart of New Caledonia's Water and Forest Service, who was active in bird conservation and paleontological work on the island. [2]
Owl pellets found in cave deposits predating human arrival to the island indicate that the New Caledonian barn owl relied almost entirely on hunting reptiles, which is consistent with New Caledonia lacking any terrestrial mammalian species at the time. Following the arrival of humans, the number of reptiles declined abruptly, whether by direct anthropic action or predation and competition with introduced commensal rodents like the Polynesian rat. The resulting lack of prey caused the New Caledonian barn owl's extinction. Afterward, New Caledonia was colonized by the common barn owl ( Tyto alba ), whose diet is rodent-based instead. [3]
Barn-owls are one of the two families of owls, the other being the true owls or typical owls, Strigidae. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. They also differ from the Strigidae in structural details relating in particular to the sternum and feet.
The barn owl is the most widely distributed group of owls in the world. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. The term may be used to describe:
The biodiversity of New Caledonia is of exceptional biological and paleoecological interest. It is frequently referred to as a biodiversity hotspot. The country is a large South Pacific archipelago with a total land area of more than 18,000 square kilometres (6,900 sq mi). The terrain includes a variety of reefs, atolls, small islands, and a variety of topographical and edaphic regions on the largest island, all of which promote the development of unusually concentrated biodiversity. The region's climate is oceanic and tropical.
Tyto is a genus of birds consisting of true barn owls, grass owls and masked owls that collectively make up all the species within the subfamily Tytoninae of the barn owl family, Tytonidae.
The Australian masked owl is a barn owl of Southern New Guinea and the non-desert areas of Australia.
Sylviornis is an extinct genus of large, flightless bird that was endemic to the islands of New Caledonia in the Western Pacific. It is considered to constitute one of two genera in the extinct family Sylviornithidae, alongside Megavitiornis from Fiji, which are related to the Galliformes, the group containing the turkeys, chickens, quails and pheasants. Sylviornis was never encountered alive by scientists, but it is known from many thousands of subfossil bones found in deposits, some of them from the Holocene, on New Caledonia and the adjacent Île des Pins. It was likely hunted to extinction shortly after the first human arrival to New Caledonia around 1500 BC.
The giant Cuban owl or giant cursorial owl (Ornimegalonyx) is an extinct genus of giant owl that measured 1.1 metres in height. It is closely related to the many species of living owls of the genus Strix. It was a flightless or nearly flightless bird and it is believed to be the largest owl that ever existed. It lived on the island of Cuba.
Tyto pollens is an extinct giant barn owl which lived in the Bahamas during the last Ice Age.
The New Caledonian gallinule was a species of bird in the family Rallidae. It was endemic to New Caledonia and probably became extinct due to hunting, habitat loss and the presence of invasive species following human settlement of the island. However a passage from an 1860 article refers to birds the size of turkeys being present in marshy areas of New Caledone, suggesting that it may have survived into historic times. The native name n'dino is thought to refer to this bird.
Tyto gigantea is an extinct barn owl from what is now Gargano, Italy, dating back to the late Miocene. From its remains, T. gigantea is suggested to have been as large as or larger than the Eurasian eagle-owl.
Tyto robusta was a prehistoric barn-owl. It lived at what is now Monte Gargano in Italy, and was an island throughout much of the Neogene when sea levels were higher. The owl's remains date back to the Miocene-Pliocene boundary 5.5 to 5 million years ago. The fossil bones are about 60% as long again as a modern barn owl, giving a total length of about 50–65 cm for T. robusta. This owl provides an interesting case study of evolution and insular gigantism.
The chickcharney is a legendary creature in the folklore of Andros Island in the Bahama Islands. It is said to live in the forests, is furry or feathered, and about 3 feet tall, with an ugly appearance resembling an owl's. In common legend, if a traveler meets a chickcharney and treats it well, they will be rewarded with good luck, while treating a chickcharney badly will result in bad luck and hard times. Sightings have continued into the present. It is said that the birds make their nest by bringing several pine trees together and making their nest in the middle. Several of these tree formations have been sighted.
The kagu or cagou is a crested, long-legged, and bluish-grey bird endemic to the dense mountain forests of New Caledonia. It is the only surviving member of the genus Rhynochetos and the family Rhynochetidae, although a second species has been described from the fossil record.
The Pindai Caves of New Caledonia are an archaeological and palaeontological site important for the study of prehistoric human settlement as well as of the Holocene fauna of the island. The Pindai area has been occupied by humans for varying periods over the last 2,800 years.
The powerful goshawk, also referred to as the greater New Caledonian goshawk, is an extinct species of bird of prey in the family Accipitridae. It was endemic to the island of New Caledonia in Melanesia in the southwest Pacific region. It was described from subfossil bones found at the Pindai Caves paleontological site on the west coast of Grande Terre. The Latin specific epithet efficax means "powerful".
The gracile goshawk is an extinct species of bird of prey in the family Accipitridae. It was endemic to the island of New Caledonia in Melanesia in the southwest Pacific region. It was described from subfossil bones found at the Pindai Caves paleontological site on the west coast of Grande Terre. The Latin specific epithet quartus means "fourth"; it was the fourth Accipiter species recorded from New Caledonia. The gracile goshawk was smaller and much less robust than its contemporary congener the powerful goshawk, remains of which were also found at the same site.
The New Caledonian ground dove is a large, extinct species of Pampusana ground dove in the pigeon family, and the largest member of its genus. It was endemic to the island of New Caledonia in Melanesia in the south-west Pacific region. It was described from subfossil bones found at the Pindai Caves paleontological site on the west coast of Grande Terre. The specific epithet refers to the slender and elongated tarsometatarsus, or lower leg bone, of the species.
The lowland kagu is a large, extinct species of kagu. It was endemic to the island of New Caledonia in Melanesia in the south-west Pacific region. It was described from subfossil bones found at the Pindai Caves paleontological site on the west coast of Grande Terre. The holotype is a right tibiotarsus, held by the Muséum national d'histoire naturelle in Paris. The specific epithet comes from the Latin orarius from its presumed lowland distribution, as opposed to its congener the living kagu R. jubatus.
