Blue-headed Parrot

One of the most colorful Pionus parrots, blue-headed parrots display a vivid cobalt blue head and neck contrasting with green body plumage and red undertail feathers. Found in humid lowland and foothill forests from southern Mexico through Central America and across northern and western South America. They inhabit forest, forest edge, and mangroves, traveling in noisy flocks to fruiting trees. Popular aviary birds for their quiet, gentle demeanor relative to many other parrots.

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.
