オンドリタイランチョウ
The cock-tailed tyrant (Alectrurus tricolor) is a striking and unusual flycatcher in the family Tyrannidae, named for the remarkable elongated, spatula-shaped outer tail feathers of the male, which can exceed the body length and are displayed during aerial courtship flights over open grasslands. The species inhabits wet and seasonally flooded grasslands, cerrado savanna, and campos in the interior of South America, including central Brazil, eastern Bolivia, Paraguay, and northeastern Argentina — not Norway, as erroneous database entries suggest. Males combine conspicuous black, white, and rufous plumage with their extraordinary tail streamers in an elaborate display to attract females on leks; females are cryptically streaked brown. The cock-tailed tyrant is a ground- and low-vegetation forager, preying on insects and other small invertebrates gleaned from grass stems and caught in aerial sallies. The species is classified as Vulnerable by the IUCN due to extensive and continuing conversion and degradation of its native Neotropical grassland habitat through intensive soy and sugarcane agriculture, cattle ranching, fire management changes, and drainage of seasonally flooded grasslands. Populations have declined significantly across much of its range, particularly in Brazil and Paraguay. The species is a flagship for threatened grassland conservation in South America, where relatively little protection has historically been directed at open-country habitats compared to forest ecosystems.
コモロルリバト
<em>Alectroenas sganzini</em>, the Comoro blue pigeon, is a medium-sized frugivorous pigeon in the family Columbidae, endemic to the Comoro Islands archipelago in the western Indian Ocean, with occasional records from Aldabra Atoll in the Seychelles. The species inhabits dense evergreen humid forest, forest edges, and heavily wooded areas, typically from sea level to higher elevations on the main islands. Like other members of the genus <em>Alectroenas</em>, it displays striking plumage featuring a bright blue-grey body, a bare red facial patch around the eye, and a short rounded tail. Biological traits such as precise average lifespan, body length, and weight remain poorly documented in consolidated scientific literature, though it is a medium-sized pigeon typical of its genus. The Comoro blue pigeon feeds primarily on fruits, figs, and other forest products, contributing to seed dispersal in native forests. Threats include ongoing habitat loss through forest clearance for agriculture and charcoal production, along with hunting pressure. <em>Alectroenas sganzini</em> is assessed as Near Threatened by the IUCN, reflecting population declines driven by deforestation and exploitation across its restricted island range in the Comoros.
