Grallistrix
The stilt-owls (''Grallistrix'') is an extinct genus of true owls which contains four species, all of which lived on the Hawaiian Islands. ''Grallistrix'' can be loosely translated as "owl on stilts". The genus received this name due to the long legs and terrestrial habits which they evolved in the absence of mammalian predators on their island homes. They fed on smaller birds such as Hawaiian honeycreepers. They were also able to fly. The owls were never seen alive by scientists and are known only from subfossil bones.

True Owl
The true owls or typical owls (family Strigidae) are one of the two generally accepted families of owls, the other being the barn owls (Tytonidae). This large family comprises 230 living or recently extinct species in 24 genera. The typical owls have a cosmopolitan distribution and are found on every continent except Antarctica. Morphology While typical owls (hereafter referred to simply as owls) vary greatly in size, with the smallest species, the elf owl, being a hundredth the size of the largest, the Eurasian eagle-owl and Blakiston's fish owl, owls generally share an extremely similar body plan.Marks, J. S.; Cannings, R.J. and Mikkola, H. (1999). "Family Strigidae (Typical Owls)". ''In'' del Hoyo, J.; Elliot, A. & Sargatal, J. (eds.) (1999). '' Handbook of the Birds of the World. Volume 5: Barn-Owls to Hummingbirds.'' Lynx Edicions. They tend to have large heads, short tails, cryptic plumage, and round facial discs around the eyes. The family is generally arboreal (with ...

Late Quaternary Prehistoric Birds
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Holocene or Late Pleistocene – and before recorded history, or more precisely, before they could be studied alive by ornithological science. They became extinct before the period of global scientific exploration that started in the late 15th century. In other words, this list basically deals with extinctions between 40,000 BC and 1500 AD. For the purposes of this article, a "bird" is any member of the clade Neornithes, that is, any descendant of the most recent common ancestor of all currently living birds. The birds are known from their remains, which are subfossil (not fossilized, or not completely fossilized). Some are also known from folk memory, as in the case of Haast's eagle in New Zealand. As the remains are not completely fossilized, they may yield organic material for molecular analyses to provide additional clues for resolving their taxonomic affil ...

Ornimegalonyx
The Cuban giant owl or giant cursorial owl (''Ornimegalonyx'') is an extinct genus of giant owl that measured in height. It is closely related to the many species of living owls of the genus ''Strix''.Feduccia, Alan (1996) "The Origin and Evolution of Birds" Yale University Press 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. The first fossil specimen was mistakenly described as a bird in the family Phorusrhacidae, in part because the bones were so large. In 1961, Pierce Brodkorb reviewed the findings and placed them properly, with the owls. Remains have been abundant throughout the island, in cave deposits from the Late Pleistocene period (126,000 to 11,700 years ago) and at least three nearly complete skeletons have been found. Taxonomy In the past, three additional species of ''Ornimegalonyx'' besides ''O. oteroi'' were regarded as valid. All were described in 1982 and include: *''Ornim ...

Tyto Pollens
''Tyto pollens'' is an extinct giant barn owl which lived in the Bahamas during the last Ice Age. Description It is only known from the partial remains of three individuals which have been collected on the islands of Little Exuma (the site was misidentified as on Great Exuma in the original literature) and New Providence. Alexander Wetmore initially described the species from fossils of a single individual from Little Exuma site which are the holotype: a complete coracoid, a proximal end of the ulna, a major metacarpal lacking the proximal end and the complete femur. The femur is 81.2mm in length. Both palaeontological sites are from before the arrival of humans (the Lucayans) to the islands. 18,000 years ago, the sea level was 120 metres lower than today and the Bahamas existed as at least five major islands, with a land mass over 10 times the modern size. Both dig sites would have been part of the same island. The fossil assembly of the period indicates that the Bahamas were muc ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moloka‘i Stilt-owl
Molokai , or Molokai (), is the fifth most populated of the eight major islands that make up the Hawaiian Islands archipelago in the middle of the Pacific Ocean. It is 38 by 10 miles (61 by 16 km) at its greatest length and width with a usable land area of , making it the fifth-largest in size of the main Hawaiian Islands and the 27th largest island in the United States. It lies southeast of Oahu across the wide Kaʻiwi Channel and north of Lānai, separated from it by the Kalohi Channel. The island's agrarian economy has been driven primarily by cattle ranching, pineapple production, sugarcane production and small-scale farming. Tourism comprises a small fraction of the island's economy, and much of the infrastructure related to tourism was closed and barricaded in the early 2000s when the primary landowner, Molokai Ranch, ceased operations due to substantial revenue losses. In Kalawao County, on the Kalaupapa Peninsula on the north coast, settlements were established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Birds Of Hawaii
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the Endling, last individual of the species, although the Functional extinction, capacity to breed and recover may have been lost before this point. Because a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. More than 99% of all species that ever Life, lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct a ...

Flightless Birds
Flightless birds are birds that through evolution lost the ability to fly. There are over 60 extant species, including the well known ratites (ostriches, emu, cassowaries, rheas, and kiwi) and penguins. The smallest flightless bird is the Inaccessible Island rail (length 12.5 cm, weight 34.7 g). The largest (both heaviest and tallest) flightless bird, which is also the largest living bird, is the ostrich (2.7 m, 156 kg). Many domesticated birds, such as the domestic chicken and domestic duck, have lost the ability to fly for extended periods, although their ancestral species, the red junglefowl and mallard, respectively, are capable of extended flight. A few particularly bred birds, such as the Broad Breasted White turkey, have become totally flightless as a result of selective breeding; the birds were bred to grow massive breast meat that weighs too much for the bird's wings to support in flight. Flightlessness has evolved in many different birds independently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
