Hahnenschwanztyrann

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.

Goldkragen-Koboldfledermaus

The Collared Sprite, known scientifically as <em>Thainycteris aureocollaris</em>, is a bat belonging to the order Chiroptera. <em>Thainycteris aureocollaris</em> is distinguished by a golden or pale collar of fur around the neck region, which gives rise to the species epithet "aureocollaris" — meaning golden-collared in Latin. The species inhabits diverse terrestrial and aquatic ecosystems. Bats of this type are generally nocturnal, roosting during the day and emerging at night to forage on flying insects using echolocation. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Sprite is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is not currently considered to be at significant risk of decline.
