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 Ground-Pine

The common ground pine, <em>Dendrolycopodium obscurum</em>, is a vascular plant belonging to the family Lycopodiaceae, a lineage of ancient clubmosses. This species is typically found across North America, with its known range encompassing Canada and the United States. As a lycophyte, <em>Dendrolycopodium obscurum</em> represents a deeply divergent lineage among land plants, distinct from mosses and ferns. The species typically grows in moist forested habitats, particularly in coniferous and mixed woodlands where humidity and leaf litter provide suitable conditions for its growth. Its upright, tree-like sporophylls give it the common name ground pine. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
