The Malagasy crowned eagle (Stephanoaetus mahery), [1] also known as the Madagascar crowned hawk-eagle, is an extinct large bird of prey endemic to Madagascar.

Contents

It has been proposed that this bird, combined with elephant bird eggs, were the source of sightings of the mythical Roc. [2]

Description

It may have been comparable in average size to the related African crowned eagle, but possibly slightly larger, with the largest female weights estimated at up to 7 kg (15 lb), or about the size of a large female golden eagle. [3]

Ecology

It probably fed on lemurs. The raptor avoidance behaviour exhibited by contemporary adult lemurs may have originated in response to this (and another now-extinct Malagasy Aquila ) eagle; extant Malagasy raptors appear to be a threat primarily to juvenile members of the large diurnal lemur species. [3] [4]

It was perhaps an apex predator of the Malagasy forests, along with the giant fossa and the Voay crocodile. It likely became extinct in the 16th century due to human overhunting of its prey. [5]

Eagle is the common name for many large birds of prey of the family Accipitridae. Eagles belong to several groups of genera, some of which are closely related. Most of the 60 species of eagle are from Eurasia and Africa. Outside this area, just 14 species can be found—2 in North America, 9 in Central and South America, and 3 in Australia.

<span class="mw-page-title-main">Bird of prey</span> Any species of bird that primarily hunt and feed on relatively large vertebrates

Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates. In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species also scavenge and eat carrion.

Elephant birds are members of the extinct ratite family Aepyornithidae, made up of flightless birds that once lived on the island of Madagascar. They are thought to have become extinct around 1000-1200 CE, probably as a result of human activity. Elephant birds comprised the genera Mullerornis, Vorombe and Aepyornis. While they were in close geographical proximity to the ostrich, their closest living relatives are kiwi, suggesting that ratites did not diversify by vicariance during the breakup of Gondwana but instead evolved from ancestors that dispersed more recently by flying.

Lemurs are wet-nosed mammals of the superfamily Lemuroidea, divided into 8 families and consisting of 15 genera and around 100 existing species. They are endemic to the island of Madagascar. Most existing lemurs are small, have a pointed snout, large eyes, and a long tail. They chiefly live in trees and are active at night.

<i>Megaladapis</i> Extinct genus of lemurs

<i>Aepyornis</i> Extinct genus of birds

Aepyornis is a genus of aepyornithid, one of three genera of ratite birds endemic to Madagascar until their extinction sometime around AD 1000. The species A. maximus weighed up to 540 kilograms (1,200 lb), and until recently was regarded as the largest known bird of all time. However, in 2018 the largest aepyornithid specimens, weighing up to 730 kilograms (1,600 lb), were moved to the related genus Vorombe. Its closest living relative is the New Zealand kiwi.

<span class="mw-page-title-main">Golden-crowned sifaka</span> A medium-sized lemur with mostly white fur, prominent furry ears, and a golden-orange crown

The golden-crowned sifaka or Tattersall's sifaka is a medium-sized lemur characterized by mostly white fur, prominent furry ears, and a golden-orange crown. It is one of the smallest sifakas, weighing around 3.5 kg (7.7 lb) and measuring approximately 90 cm (35 in) from head to tail. Like all sifakas, it is a vertical clinger and leaper, and its diet includes mostly seeds and leaves. The golden-crowned sifaka is named after its discoverer, Ian Tattersall, who first spotted the species in 1974. However, it was not formally described until 1988, after a research team led by Elwyn L. Simons observed and captured some specimens for captive breeding. The golden-crowned sifaka most closely resembles the western forest sifakas of the P. verreauxi group, yet its karyotype suggests a closer relationship with the P. diadema group of eastern forest sifakas. Despite the similarities with both groups, more recent studies of its karyotype support its classification as a distinct species.

The narrow-striped mongoose or narrow-striped vontsira is a member of the family Eupleridae endemic to Madagascar. It inhabits the western Madagascar succulent woodlands and northern Madagascar spiny thickets in western and southwestern Madagascar, where it lives from sea level to about 125 m (410 ft) between the Tsiribihina and Mangoky rivers. In Malagasy it is called bokiboky.

<i>Cryptoprocta spelea</i> Extinct species of carnivoran from Madagascar

Cryptoprocta spelea, also known as the giant fossa, is an extinct species of carnivore from Madagascar in the family Eupleridae which is most closely related to the mongooses and includes all Malagasy carnivorans. It was first described in 1902, and in 1935 was recognized as a separate species from its closest relative, the living fossa. C. spelea was larger than the fossa, but otherwise similar. The two have not always been accepted as distinct species. When and how C. spelea became extinct is unknown; there is some anecdotal evidence, including reports of very large fossas, that there is more than one surviving species.

Henst's goshawk is a species a bird of prey in the family Accipitridae. It is a large, diurnal bird endemic to the island of Madagascar. It is an obligate forest species that occurs at very low densities on the island and is rarely seen. It can only occupy the primary and secondary forests found within the island. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and plantations.

The northern sportive lemur, also known as the Sahafary sportive lemur or northern weasel lemur, is a species of lemur in the family Lepilemuridae. It is endemic to Madagascar. As a result of severe ecological and human pressures, the lemur is classified as Critically Endangered (CR) by the IUCN Red List.

<i>Babakotia</i> Extinct genus of lemurs

Babakotia is an extinct genus of medium-sized lemur, or strepsirrhine primate, from Madagascar that contains a single species, Babakotia radofilai. Together with Palaeopropithecus, Archaeoindris, and Mesopropithecus, it forms the family Palaeopropithecidae, commonly known as the sloth lemurs. The name Babakotia comes from the Malagasy name for the indri, babakoto, to which it and all other sloth lemurs are closely related. Due to its mix of morphological traits that show intermediate stages between the slow-moving smaller sloth lemurs and the suspensory large sloth lemurs, it has helped determine the relationship between both groups and the closely related and extinct monkey lemurs.

<span class="mw-page-title-main">Subfossil lemur</span> Lemurs from Madagascar that are represented by recent (subfossil) remains

Subfossil lemurs are lemurs from Madagascar that are represented by recent (subfossil) remains dating from nearly 26,000 years ago to approximately 560 years ago. They include both extant and extinct species, although the term more frequently refers to the extinct giant lemurs. The diversity of subfossil lemur communities was greater than that of present-day lemur communities, ranging from as high as 20 or more species per location, compared with 10 to 12 species today. Extinct species are estimated to have ranged in size from slightly over 10 kg (22 lb) to roughly 160 kg (350 lb). Even the subfossil remains of living species are larger and more robust than the skeletal remains of modern specimens. The subfossil sites found around most of the island demonstrate that most giant lemurs had wide distributions and that ranges of living species have contracted significantly since the arrival of humans.

<span class="mw-page-title-main">Crowned eagle</span> Species of bird

The crowned eagle, also known as the African crowned eagle or the crowned hawk-eagle, is a large bird of prey found in sub-Saharan Africa; in Southern Africa it is restricted to eastern areas. Its preferred habitats are principally riparian woodlands and various forests. The crowned eagle is the only extant member of the genus Stephanoaetus. A second species, the Malagasy crowned eagle became extinct after humans settled on Madagascar.

Ampasambazimba is a mountain peak and subfossil site in Madagascar, most known for being the site of the remains of the extinct giant sloth lemur Archaeoindris.
