チョコアメリカムシクイ

The Choco Warbler (Myiothlypis chlorophrys) is a small, ground-associated warbler in the family Parulidae (New World warblers), endemic to the subtropical Andean foothills of western Ecuador in the Chocó biogeographic region. It belongs to the diverse genus Myiothlypis (formerly placed in Basileuterus), a group of largely terrestrial neotropical warblers that forage in the undergrowth of humid montane forests. The Choco Warbler is characterised by olive-green upperparts, yellow underparts, and a distinctive supercilium pattern on the head. It inhabits the dense undergrowth of humid foothill and lower montane forest at elevations between approximately 600 and 1,500 metres, foraging close to the ground among fallen leaves and low shrubs for small invertebrates. Its range appears largely restricted to southwestern and northwestern Ecuador in the humid Pacific slope forest zone, though the precise distribution boundary with related species is still being refined taxonomically. The IUCN classifies this species as Least Concern. Ecuador's Pacific slope forests face considerable pressure from agricultural expansion — particularly banana, cacao, and palm oil cultivation — and human settlement, though the species appears to tolerate some degree of forest degradation within its range.

Common Neacomys

<em>Neacomys spinosus</em>, the common neacomys or spiny neacomys, is a small rodent in the family Cricetidae found in South America. This ground-dwelling mouse is characterized by its distinctively spiny fur, an adaptation that may provide protection against predators. <em>Neacomys spinosus</em> typically inhabits tropical lowland and montane forests, forest edges, and adjacent scrubby vegetation in northwestern South America, with its geographic range including Colombia and surrounding countries. The species forages on the forest floor and in low vegetation, and is believed to consume seeds, plant material, and invertebrates, although specific dietary data are limited. It is currently assessed as Least Concern by the IUCN, with populations considered stable across its range, though ongoing deforestation in the Amazonian and Andean foothills may present long-term threats. Biological traits such as lifespan, body size, and diet remain poorly documented for this species across its full range. <em>Neacomys spinosus</em> plays a role in seed dispersal and forms part of the prey base for small mammalian and avian predators in its tropical forest ecosystems.
