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.

Common Club Rush Rust

<em>Puccinia scirpi</em>, commonly known as the common club rush rust, is a parasitic fungus in the family Pucciniaceae, belonging to the order of rust fungi. This species occurs across Asia and Europe, where it typically infects club rushes and related sedge-family plants in the genus <em>Scirpus</em> and allied genera. Like other rust fungi, <em>Puccinia scirpi</em> is an obligate biotroph, meaning it can only complete its life cycle on living host tissue. Infections often produce orange-brown pustules on the stems and leaves of host plants, releasing urediniospores that spread the fungus to neighboring hosts. The species typically colonizes wetland habitats such as marshes, fens, and the margins of rivers and lakes where club rushes are abundant. Biological traits of this species remain poorly documented in the scientific literature.
