Habitat & Geographic Range

Cock-tailed Tyrant

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common pricklypear

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and deserts and xeric shrublands, among 9 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (15 countries), Asia (10 countries), Europe (7 countries), North America (Nicaragua, Panama, United States), Oceania and the Pacific (9 countries), and South America (Brazil, Venezuela).

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 pricklypear

The Common Pricklypear, <em>Opuntia monacantha</em>, is a cactus in the family Cactaceae with a remarkably broad global distribution, naturalized across Africa, Asia, Europe, and throughout the Americas and Oceania. Native to South America, it has been introduced widely and is considered invasive in parts of its non-native range. The species is characterized by its flat, oval to elongated green cladodes bearing sparse but long spines and dense glochids at each areole. <em>Opuntia monacantha</em> typically grows in dry, disturbed habitats including coastal areas, roadsides, agricultural margins, and degraded scrublands, thriving in full sun and well-drained soils. It produces yellow flowers and small purplish-red fruits that are consumed by birds and mammals, facilitating seed dispersal across its wide range. The plant utilizes CAM photosynthesis, allowing it to minimize water loss in arid conditions. In some regions, the species is cultivated for its edible fruits and as a livestock fodder. It is assessed as Least Concern on the IUCN Red List given its abundance and broad distribution. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
