The Colombian weasel (Neogale felipei), also known as Don Felipe's weasel, is a very rare species of New World weasel only known with certainty from the departments of Huila and Cauca in Colombia [2] and nearby northern Ecuador (where it is only known from a single specimen). [1] Both its scientific and alternative common name honours the mammalogist Philip "Don Felipe" Hershkovitz. [3]
It appears to be largely restricted to riparian habitats at an altitude of 1,100 to 2,700 m (3,600 to 8,900 ft). There is extensive deforestation within its limited distribution within the northern Andes of Colombia and Ecuador, and with less than 10 known specimens, [1] it is probably the rarest carnivoran in South America. [4] It is considered vulnerable by the IUCN. [1]
It is the second-smallest living carnivoran on average, being only slightly larger than the least weasel (Mustela nivalis) and slightly smaller than the stoat or ermine (M. erminea). [5] The upperparts and tail are blackish-brown, while the underparts are orange-buff. [4]
The species was formerly only known from specimens until the first photo of a living individual was taken in 2011 by an amateur naturalist who found one trapped in his parents' house; the weasel subsequently escaped to the outdoors. The image was uploaded to iNaturalist in 2018, where it gained widespread attention. [6] [7]
Originally described in the genus Mustela , a 2021 study reclassified into the genus Neogale along with two other former Mustela species, as well as the two species formerly classified in Neovison . [8]
N. felipei has an elongated body with an average length of 22 cm (8.7 in), and a tail 11.5 cm (4.5 in) long. Weight ranges between 120 and 150 g (4.2 and 5.3 oz). N. felipei has a dark dorsal color with no variation, ventrally the weasel has a light orange color with gradual fading of color up to the head. Hair color from the tail to the nose is uniform with no striping or spotting. N. felipei has an inflated auditory bulla located near the dorsal midline on the body, along with a wide mesopterygoid fossa. The soles of the feet lack any fur, and extensive webbing is located on the second, third, and fourth digits, suggesting a semi-aquatic lifestyle. [9]
N. felipei is one of the least studied carnivore species in the Americas. Photos taken of a Colombian weasel by Juan de Roux are the first known photos of a living Colombian weasel. These tiny carnivores are thought to maintain a larger geographical range that currently known. Reports of sightings have placed N. felipei in the mountain ranges of western Colombia to northern Ecuador. N. felipei was originally thought to be endemic to Colombia however recent specimens have been collected in Ecuador that have since proven this thought wrong. Distribution and habitat modeling surveys have been able to predict that N. felipei is distributed between 20 protected areas in Colombia, and 14 in Ecuador along with three previously known locations in both countries, the majority of these locations lie in protected areas of the forest.
From geographic modeling, and collected specimens it has been concluded that Neogale felipei lives in largely riparian habitats, primarily staying close to rivers, streams, and along the shorelines of other natural water sources. Since this habitat lies in an elevation range of 1,100 to 2,700 m (3,600 to 8,900 ft) it is classified as being in a "cloud forest" consisting of 100% humidity adding to the riparian habitat.
N. felipei is a carnivorous mammal that preys primarily on fish, other small aquatic animals, and small terrestrial mammals. Hunting is aided by the use of webbed feet and camouflaged fur.
Neogale felipei has been recognized by the IUCN as being vulnerable and having a decreasing population. However, due to rarity of sighting, and deforestation of known habitat it remains unclear as to the true numbers of individuals that make up the population. [1]
The Mustelidae are a diverse family of carnivoran mammals, including weasels, badgers, otters, polecats, martens, grisons, and wolverines. Otherwise known as mustelids, they form the largest family in the suborder Caniformia of the order Carnivora with about 66 to 70 species in nine subfamilies.
Weasels are mammals of the genus Mustela of the family Mustelidae. The genus Mustela includes the least weasels, polecats, stoats, ferrets, and European mink. Members of this genus are small, active predators, with long and slender bodies and short legs. The family Mustelidae, or mustelids, is often referred to as the "weasel family". In the UK, the term "weasel" usually refers to the smallest species, the least weasel (M. nivalis), the smallest carnivoran species.
The kinkajou is a tropical rainforest mammal of the family Procyonidae related to olingos, coatis, raccoons, and the ringtail and cacomistle. It is the only member of the genus Potos and is also known as the "honey bear". Though kinkajous are arboreal, they are not closely related to any other tree-dwelling mammal group.
The long-tailed weasel, also known as the bridled weasel, masked ermine, or big stoat, is a species of weasel found in North, Central, and South America. It is distinct from the short-tailed weasel, also known as a "stoat", a close relation in the genus Mustela that originated in Eurasia and crossed into North America some half million years ago; the two species are visually similar, especially the black tail tip.
The least weasel, little weasel, common weasel, or simply weasel is the smallest member of the genus Mustela, family Mustelidae and order Carnivora. It is native to Eurasia, North America and North Africa, and has been introduced to New Zealand, Malta, Crete, the Azores, and São Tomé. It is classified as least concern by the IUCN, due to its wide distribution and large population throughout the Northern Hemisphere.
The European mink, also known as the Russian mink and Eurasian mink, is a semiaquatic species of mustelid native to Europe.
Mountain coatis are two species of procyonid mammals from the genus Nasuella. Unlike the larger coatis from the genus Nasua, mountain coatis only weigh 1.0–1.5 kilograms (2.2–3.3 lb) and are endemic to the north Andean highlands in South America.
The sea mink is a recently extinct species of mink that lived on the eastern coast of North America around the Gulf of Maine on the New England seaboard. It was most closely related to the American mink, with continuing debate about whether or not the sea mink should be considered a subspecies of the American mink or a species of its own. The main justification for a separate species designation is the size difference between the two minks, but other distinctions have been made, such as its redder fur. The only known remains are bone fragments unearthed in Native American shell middens. Its actual size is speculative, based largely on tooth remains.
The Amazon weasel, also known as the tropical weasel, is a species of New World weasel native to South America. It was first identified from a museum specimen mislabelled as coming from Africa, hence the scientific name.
The western mountain coati or western dwarf coati is a small procyonid, found in cloud forest and páramo at altitudes of 1,300–4,250 metres (4,270–13,940 ft) in the Andes of Colombia and Ecuador. A population discovered in the Apurímac–Cuzco region of southern Peru has tentatively been identified as the western mountain coati, but may represent an undescribed taxon.
The back-striped weasel, also called the stripe-backed weasel, is a weasel widely distributed in Southeastern Asia. It is listed as Least Concern on the IUCN Red List in view of its presumed large population, occurrence in many protected areas, apparent tolerance to some degree of habitat modification and hunting pressure.
The mountain weasel, also known as the pale weasel, Altai weasel or solongoi, primarily lives in high-altitude environments, as well as rocky tundra and grassy woodlands. This weasel rests in rock crevices, tree trunks, and abandoned burrows of other animals or the animals it previously hunted. The home range size of this animal is currently unknown. Geographical distribution for this species lies in parts of Asia from Kazakhstan, Tibet, and the Himalayas to Mongolia, northeastern China, and southern Siberia. The most common area for this species, however, is Ladakh, India. The conservation status, according to the IUCN, is near threatened because it is considered to be in significant decline and requires monitoring mainly because of habitat and resource loss.
The banded palm civet, also called the banded civet, is a viverrid native to Indomalaya. They primarily inhabit lowland conifer habitat, which is under threat from encroaching human activity. It is estimated the population of the banded palm civet has decreased by around 30% in just three generations. Banded palm civets are usually approximately the size of a domestic cat; their fur is pale but with dark bands on the back. They are believed to be closely related to Hose's palm civets, which are similar in appearance and distribution.
Johnston's genet is a genet species native to the Upper Guinean forests. As it is threatened by deforestation and conversion of rainforest to agriculturally and industrially used land, it is listed as Near Threatened on the IUCN Red List.
The South American coati, also known as the ring-tailed coati, is a coati species and a member of the raccoon family (Procyonidae), found in the tropical and subtropical parts of South America. An adult generally weighs from 2–7.2 kg (4.4–15.9 lb) and is 85–113 cm (33–44 in) long, with half of that being its tail. Its color is highly variable and the rings on the tail may be only somewhat visible, but its most distinguishing characteristic is that it lacks the largely white snout of its northern relative, the white-nosed coati.
The Choco broad-nosed bat is a species of bat in the family Phyllostomidae. It is native to Colombia, Panama, and Ecuador, where it is found in the Choco region lowlands. It is threatened by habitat loss. In 2013, Bat Conservation International listed this species as one of the 35 species of its worldwide priority list of conservation.
The Malayan weasel or Malay weasel is a weasel species native to the Malay Peninsula and the islands of Sumatra and Borneo. It is listed as Least Concern on the IUCN Red List.
Neogale is a genus of mustelid native to the Americas, ranging from Alaska south to Bolivia. Members of this genus are known as New World weasels.
