Black-mantled Tamarin

The Black-mantled Tamarin (Leontocebus nigricollis) is a species in the genus Leontocebus. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

Colombian Crake

<em>Neocrex colombiana</em>, commonly known as the Colombian Crake, is a bird species belonging to the genus <em>Neocrex</em> within the family Rallidae, a group of typically secretive marsh and wetland birds. This species is classified as Data Deficient, indicating that current information is insufficient to accurately determine its conservation status, and that further survey work is required to understand its population size and trend. It has been documented in Colombia and Ecuador, where it inhabits various environmental settings consistent with rallid ecology, including wetlands, marshy grasslands, and dense vegetation near water. Rails and crakes in this family are generally omnivorous, feeding on invertebrates, seeds, and small vertebrates, though specific dietary records for this species have not been documented. Biological traits of this species remain poorly documented in the scientific literature. The secretive nature of rallid birds, combined with their preference for dense habitats, makes population surveys challenging. Comprehensive field surveys using acoustic monitoring are considered essential for improving knowledge of <em>Neocrex colombiana</em>.
