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 Extinguisher-moss

<em>Encalypta vulgaris</em>, the common extinguisher moss, is a acrocarpous moss in the family Encalyptaceae, classified as Vulnerable by the IUCN Red List, indicating a concerning decline in populations across parts of its European range. The species is documented in Belgium, Denmark, Luxembourg, Norway, and Portugal, where it is native to European calcareous habitats. <em>Encalypta vulgaris</em> typically grows on dry to moist calcareous rocks, soil banks, old walls, and disturbed ground with base-rich substrates, often in open or semi-shaded microhabitats. The common name refers to the distinctive elongated calyptra, a cap-like structure that covers the developing sporophyte and resembles an old-fashioned candle snuffer or extinguisher. The calyptra is persistent and fringed at its base, a diagnostic feature of the genus <em>Encalypta</em>. This moss is sensitive to nitrogen pollution and habitat disturbance, and its Vulnerable status reflects the loss and degradation of calcareous grasslands and rock habitats across Europe due to agricultural intensification, urban development, and changing land management. It plays a role in soil stabilization and moisture retention in the rocky and disturbed habitats it colonizes. Conservation of calcareous habitats is essential for maintaining populations of this and many other specialist plant and lichen species. Biological traits of this species remain poorly documented in the scientific literature.
