R
starts withRed-crested tree-rats have a woolly, soft, and long coat. They are mainly rufous. The hair on the dorsal region is of intense red coloring, and a large portion of the tail hair is black (basal), but the last two-fifths of the tail are white. Their ears are small and light brown, and feature tufts of long hair on the inner surface, but lack hair on the outer surface. Between the eye and the ear, there is a tuft of long black hair. The thin whiskers can reach up to 13 cm (5 in) long, and there is a strip of red fur around the neck. The upper surfaces of the front and rear legs are covered in a pale gray coat, and the hind legs are very short and wide. The feet lack small tubercles and the thumb is covered by a nail. Red-crested tree-rats have large eyes, which is consistent with their nocturnal behavior. Young individuals have a grey coat. During the transition to the adult intense red coat, molting begins at the anterior region and moves backward.
Red-crested tree-rats are native to the Sierra Nevada de Santa Marta, an isolated mountain range in northern Colombia. This mountainous region has high levels of biodiversity and is considered a unique place in the world.
Little is known about the habits of Red-crested tree-rats. They are nocturnal animals. They can easily climb a vertical wooden surface.
The diet of Red-crested tree-rats is unknown, but it is assumed that they feed on plant matter such as fruits or seeds.
Information about the reproductive behavior of this species is scarce.
The threats facing these small rodents are unknown but the natural habitat of the species is believed to suffer degradation. Much of its potential area is infested with feral cats (who feed on fauna), and climate change is a long-term threat to the species.
The IUCN Red List and other sources don’t provide the number of the Red-crested tree-rat total population size. Currently, this species is classified as Critically Endangered (CR) on the IUCN Red List.
