Cock-tailed Tyrant

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.

<em>Comatricha tenerrima</em> is a myxomycete belonging to the genus <em>Comatricha</em>, class Myxomycetes, order Stemonitidales. The species epithet tenerrima, meaning very delicate, likely refers to the particularly fine structure of its capillitium or sporangial walls. Like other members of the genus, <em>C. tenerrima</em> inhabits moist, decaying substrates such as rotting wood and leaf litter in forest environments, where the plasmodial feeding stage actively moves across surfaces to consume bacteria, yeasts, and organic particles. The transition to the reproductive stage results in the formation of stalked sporangia releasing spores for aerial dispersal. No geographic range information is provided in the current record. The species does not possess conventional biological traits such as body size or mass, and no quantitative data are available. <em>C. tenerrima</em> has not been assessed on the IUCN Red List.
