Alagoas curassow



The last (unconfirmed) watching of this species was within the late Eighties and it's currently Extinct within the Wild. There area unit 2 captive populations and, associate apparently appropriate forest remnant has been known for future intro efforts.

83-89 cm. giant cracid with casque-like bill. All black animal material, glossed purplish-blue, except chestnut at base of leg bone, vent and undertail-coverts, and narrowly brown-tipped tail. Slightly swollen red bill with whitish tip, red legs and toes and achromatic iris. tiny crescent of clean greyish-white skin on rear ear-coverts. Similar spp. solely genus member with clean skin on ear-coverts. Congenerics have white tips to tail. Most closely resembles Razor-billed gallinacean M. tuberosa, however bill not as large and is two-toned. Voice Apparently undescribed, however males apparently share booming calls of congenerics (L. F. Silveira in litt. 2012)

Mitu mitu has been nearly definitely extirpated from Alagoas and city, north-east Brazil. A report from north Bahia is unreliable. It went unreported between the mid-17th century, once found in city, and 1951, once rediscovered around São Miguel dos Campos, Alagoas. Since the first Nineteen Seventies, there area unit records from four forests during this region. Numbers were in all probability as few as twenty, even within the Sixties (del Hoyo 1994). the foremost recent reports were of afraid people in 1984 and maybe 1987 or 1988.

Population justification
A captive population, at the start established in First State Janeiro|Rio|city|metropolis|urban center} de Janeiro in 1977, numbered forty four in 2000. there have been a hundred thirty birds in 2 aviaries in 2008, some thirty fifth of that area unit hybrids with M. tuberosum.

Ecology
It was apparently confined to lowland primary forest, wherever it absolutely was proverbial to require fruit of Phyllanthus, genus Eugenia and "mangabeira". It lays 2 or 3 eggs in captivity, with one feminine breeding for the primary time once she was 2 years previous (del Hoyo 1994).

Threats
The extinction of this species was forecast nearly as earlier as its discovery. incessant clearance of its lowland forests, primarily for sugarcane, and cooking have brought it to the verge of extinction. Sugarcane demand accrued dramatically within the late Nineteen Seventies, due to a government programme to extend fuel alcohol production, fast the destruction of remaining environs. Pesticide-use in cane fields close existent forest may additionally  have had a harmful result. The last remaining space of moderately intensive lowland forest within the region was just about entirely cleared inside six months within the late Eighties, whereas continued  searching served solely to exacerbate the species's decline.

Conservation actions afoot
CITES Appendix I and guarded underneath Brazilian law. a non-public captive population, supplemented from the wild, was established in 1977, and divided between 2 standard aviculturists in 1999 once it numbered forty four, with ten eggs in artificial incubation (Atualidades Ornitológicas 93: 11). A thirty km2 forest remnant in Alagoas, Usina Junipero Serra Grande and Usina Leão and another web site, Fazenda Petropolis, in Usina Santo Antonio are known for potential intro tries (Atualidades Ornitológicas 93: eleven, Grau et al. 2003). alternative efforts, in 1983-1985, to capture wild people for a captive-breeding population failing. Searches of remaining forest fragments in 2001 did not notice any trace of the species (Silveira et al. 2003). The genetic composition of the captive population has been studied by Mercival Francisco and a registry created (L. F. Silveira in litt. 2012).

Conservation actions planned
Continue with the captive-breeding programme so as to present the species. make sure the integrity of forest at Usina Junipero Serra Grande and Usina Leão. Engender pride within the species to lower the chance of searching once intro is begun.
