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.
