Jaguarundi

Characterized by a remarkably elongated and slender body with comparatively short limbs and a very long, tapering tail, this medium-sized felid presents a physical silhouette that strongly resembles a mustelid or an otter. The head is small, flattened, with short, rounded ears and amber-colored eyes. This species exhibits a body weight typically ranging from 3.5 to 9 kilograms, with a head-and-body length of 53 to 77 centimeters and a tail extending an additional 31 to 60 centimeters to its total length. Its coat is short, dense, and uniform in coloration, completely lacking spots or stripes in adult individuals. It displays a striking color polymorphism, with two primary color morphs: a grey morph that ranges from charcoal grey to brownish-black, and a red morph spanning chestnut, bright reddish-yellow, or tawny. Both color variations can occur within the same litter, which historically led taxonomists to erroneously classify them as distinct species.

Geographical distribution: Occupies a vast geographic range in the Americas, stretching from the southern tip of Texas in the United States and coastal regions of Mexico, down through Central America, and extending as far south as central Argentina in South America. Despite this extensive distribution, population densities are generally low, and the species has become highly fragmented or locally extinct in the northernmost parts of its range, with virtually no recent confirmed sightings in the US territory over the last decades.

Habitat: Displays exceptional ecological plasticity but exhibits a strong preference for dense, brushy cover. It is commonly found in tropical rainforests, deciduous dry forests, thorn scrublands, wet savannas, swampy areas, wetlands, and riparian thickets. It generally avoids cold, open montane regions, preferring lowland areas below 2,000 meters in elevation, although specimens have occasionally been documented at elevations up to 3,200 meters in the Andean range. It shows a moderate tolerance for human-altered landscapes, utilizing agricultural fields, pasture edges, and secondary growth forests provided there is sufficient dense understory cover for concealment.

Feeding: Classified as an opportunistic and generalist carnivore, tailoring its diet to the local availability of terrestrial prey. It feeds primarily on small mammals, especially rodents from the genera Sigmodon and *Oryzomys, as well as ground-dwelling birds of small to medium size. It also consumes a significant proportion of reptiles, including lizards and non-venomous snakes, along with amphibians and large insects. Occasionally, the ingestion of plant matter, such as grass and fallen wild fruits, has been documented, and in human-dominated landscapes, it may prey on domestic poultry, leading to frequent conflict with local farmers.

Behavior: Unlike most other neotropical wild cats, it is predominantly diurnal and crepuscular, with peaks of activity occurring in the early morning and late afternoon hours. It is primarily a solitary hunter, although it is observed in pairs more frequently than other small felids in the region. Although it is an agile climber and a capable swimmer, it conducts almost all of its hunting activities and movements on the ground. This species is notable for its remarkably diverse and complex vocal repertoire for a solitary cat, utilizing at least 13 distinct vocalizations including whistles, bird-like chirps, purrs, and yaps for intraspecific communication.

Reproduction: Breeding is not strictly seasonal in tropical regions, allowing mating to occur year-round, whereas populations at the latitudinal extremes of its range may show reproductive peaks tied to local climatic changes. The female´s estrous cycle lasts approximately 3 to 5 days. Following a gestation period of 70 to 75 days, the female gives birth to a litter of 1 to 4 kittens. Dens are established in well-hidden locations, such as dense brush, hollow logs, or thick grassy clumps. The kittens are born blind and feature transient spotting on their underparts, which fades completely as they mature. They begin consuming solid food at around three weeks of age and reach sexual maturity between 2 and 3 years of age.

Conservation status: Listed globally as Least Concern (LC) on the IUCN Red List of Threatened Species. However, its populations are experiencing an overall declining trend due to severe anthropogenic pressures, including habitat loss from agricultural expansion, forest fragmentation, road mortality, and retaliatory killing due to poultry predation. In several countries within its range, such as Mexico and the United States, it is classified under stricter national threat categories like Endangered, and is listed under Appendix I of CITES for Central and North American populations, and Appendix II** for South American populations.
