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.

Duck Hawk

The fastest animal on the planet, peregrine falcons achieve aerial dive speeds exceeding 320 km/h when stooping on prey, stunning or killing birds in flight with a blow from their feet. Found on every continent except Antarctica in diverse habitats from Arctic tundra to tropical rainforest. Nearly extinct in North America and Europe from DDT poisoning in the 1960s–70s, peregrines recovered dramatically following pesticide bans and successful urban nesting programs.
