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.

Cokerite Palm

The Cokerite Palm (Attalea maripa), also known as Maripa Palm or Inajá, is a solitary, tall-growing feather palm in the family Arecaceae, distributed across the lowland rainforests, forest edges, and floodplain forests of Amazonian South America, primarily in Brazil and Colombia, with additional records from Venezuela, Guyana, Suriname, French Guiana, Peru, Bolivia, and Ecuador. Trees typically reach 15–25 metres in height, producing large pinnate fronds and impressive clusters of ovoid fruits with an oily, yellow-orange outer mesocarp surrounding a hard-shelled nut. The palm is widely used by indigenous and traditional communities throughout Amazonia: the oil-rich mesocarp of the fruits is eaten fresh and used to produce a nutritious food paste; the apical bud (palm heart) is consumed; the young leaves are used for basket weaving and thatching; and the trunk wood serves in construction. Attalea maripa frequently regenerates vigorously in disturbed forest and pasture margins, indicating tolerance for light disturbance. It plays an important ecological role as a food source for large frugivores including tapirs, peccaries, and macaws that help disperse its large seeds. The species is assessed as Least Concern by the IUCN, with stable populations across its broad Amazonian range.
