Habitat & Geographic Range

Chestnut-fronted Macaw

Habitat

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

Range

Widely distributed across Europe (Belgium, Norway), North America (United States), and South America (Colombia, Ecuador, Venezuela).

Common Sensitive-Plant

Habitat

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

Range

Widely distributed across Africa (22 countries), Asia (19 countries), Europe (Spain, Sweden), North America (5 countries), Oceania and the Pacific (13 countries), and South America (Brazil, Colombia).

Chestnut-fronted Macaw

A medium-sized macaw of Central and South American tropical forests from southern Mexico to Bolivia and Brazil, chestnut-fronted macaws have predominantly green plumage with a chestnut forehead, red shoulder patches, and blue flight feathers. The smallest of the true macaws, they inhabit forest edges, savannas, and secondary woodland and often raid crops, making them locally unpopular with farmers. They are popular aviary birds, but wild populations face pressure from trapping and deforestation.

Common Sensitive-Plant

<em>Mimosa pudica</em>, the common sensitive plant, is a pantropical annual or perennial herb in the family Fabaceae, order Fabales, native to South and Central America but now naturalized across tropical Africa, Asia, Europe, North America, Oceania, and South America. This species is best known for its rapid thigmonastic leaf movements — leaflets and petioles fold inward and droop within seconds of being touched or disturbed, a response thought to deter herbivores and reduce water loss. <em>Mimosa pudica</em> typically grows as a sprawling, prickly herb in disturbed habitats including roadsides, pastures, and degraded lands, and produces small pink to purple spherical flower heads. The seeds are dispersed via various vectors and germinate readily, contributing to its success as an invasive species in many regions outside its native range. The species is listed as Least Concern by the IUCN, reflecting its wide distribution and high adaptability. Biological traits for this species remain poorly documented in the scientific literature in terms of standardized averages for lifespan, plant height, and weight, though its growth habit and ecological behavior as a pioneer and potential invasive are well characterized.
