Colombian Oldfield Mouse

<em>Thomasomys dispar</em>, commonly known as the Colombian Oldfield Mouse, is a small rodent species belonging to the genus <em>Thomasomys</em> within the family Cricetidae. This species is classified as Data Deficient, indicating that insufficient information is currently available to evaluate its conservation status with confidence. It has been documented in Colombia, where it inhabits diverse terrestrial and aquatic-adjacent environments. Members of the genus <em>Thomasomys</em> are typically associated with high-altitude Andean habitats, including páramo grasslands, shrublands, and montane forest edges, where they occupy ground-level microhabitats and burrow in soft soils. These mice are generally omnivorous, consuming seeds, plant material, and invertebrates, though specific dietary data for <em>Thomasomys dispar</em> have not been recorded. Biological traits of this species remain poorly documented in the scientific literature. The Data Deficient classification highlights the need for targeted surveys in Colombian Andean regions to determine population size, distribution, and the ecological requirements of this poorly known rodent.

Scaly-naped Parrot / Scaly-naped Amazon

A large, predominantly green amazon parrot with distinctive dark-scaled nape feathers and a patch of red on the wing, scaly-naped amazons inhabit humid montane forests of the northern and central Andes in Colombia, Venezuela, Ecuador, and Peru at elevations of 600–3,000 meters. Relatively little known compared to other amazons, they are found in pairs or small flocks feeding on seeds, fruit, and flowers in cloud forest. Listed as Least Concern.
