Ocelot – Leopardus Pardalis
The ocelot (/ˈɒsəlɒt/; Leopardus pardalis), also known as the dwarf leopard, is a wild cat distributed extensively within South America including the islands of Trinidad and Margarita, Central America, and Mexico. It has been reported as far north as Texas. North of Mexico, it is found regularly only in the extreme southern part of Texas, although there are rare sightings in southern Arizona.
The ocelot is similar in appearance to a domestic cat. Its fur resembles that of a clouded leopard or jaguar and was once regarded as particularly valuable. As a result, hundreds of thousands of ocelots were once killed for their fur. The feline was classified as a vulnerable species from 1972 until 1996, and is now listed as Least Concern on the IUCN Red List.
The ocelot’s genus Leopardus consists of nine species similar to the ocelot, such as Geoffroy’s cat and the margay, which are also endemic to South and Central America. All of the cats in Leopardus are spotted, lithe, and small, with the ocelot being the biggest.
The following are the currently recognized subspecies of ocelot:
- Leopardus pardalis pardalis, Amazon Rainforest
- Leopardus pardalis aequatorialis, northern Andes and Central America
- Leopardus pardalis albescens, eastern Mexico, southern Texas
- Leopardus pardalis melanurus, Venezuela, Guyana, Trinidad
- Leopardus pardalis mitis, Argentina, Paraguay
- Leopardus pardalis nelsoni, southwestern Mexico
- Leopardus pardalis pseudopardalis, Colombia
- Leopardus pardalis puseaus, Ecuador
- Leopardus pardalis sonoriensis, northwestern Mexico, southern Arizona
- Leopardus pardalis steinbachi, Bolivia
Certain ocelot subspecies are officially endangered, although the species as a whole is not.
The ocelot ranges from 68 to 100 centimetres (27 to 39 in) in length, plus 26 to 45 centimeters (10 to 18 in) in tail length, and typically weighs 8 to 18 kilograms (18 to 40 lb), although much larger individuals have occasionally been recorded, making it the largest of the Leopardus genus. It has sleek, smooth fur, rounded ears and relatively large front paws. While similar in appearance to the oncilla and margay, which inhabit the same region, the ocelot is larger.
The coat pattern of ocelots can vary, being anything from cream to reddish-brown in color, or sometimes grayish, and marked with black rosettes. In many individuals, some of the spots, especially on the back, blend together to form irregular curved stripes or bands. The fur is short, and paler than the rest of the coat beneath. There are also single white spots, called ocelli, on the backs of the ears. Two black stripes line both sides of the face, and the long tail is banded by black.
Ecology and behavior
The ocelot is mostly nocturnal and territorial. It will fight fiercely, sometimes to the death, in territorial disputes. In addition, the cat marks its territory with urine. Like most felines, it is solitary, usually meeting only to mate. However, during the day it rests in trees or other dense foliage, and occasionally shares its spot with another ocelot of the same sex. Males occupy territories of 3.5 to 46 square kilometers (1.4 to 17.8 sq mi), while females occupy smaller, non-overlapping territories of 0.8 to 15 square kilometers (0.31 to 5.79 sq mi). Territories are marked by urine spraying and by leaving feces in prominent locations, sometimes favoring particular latrine sites.
Barro Colorado Island holds the highest ocelot density recorded: between 1.59-1.74 ocelots per km2 (0.62 mi2), probably due to high number of prey, artificial lake, increased protection from poaching, and lack of large predators, such as cougars and jaguars, though they temporarily visit the island.
Ocelots hunt over a range of 18 km2 (6.9 sq mi), taking mostly small animals, including mammals, lizards, turtles, and frogs, crabs, birds, and fish. Almost all of the prey that the ocelot hunts is far smaller than itself, with rodents, rabbits, and opossums forming the largest part of the diet. Results of studies suggest that it follows and finds prey via odor trails, but the ocelot also has very good vision, including night vision.
Reproduction and life cycle
Ocelots mate at any time of year, but have litters only once every other year. The female may mate again shortly after losing a litter. When in estrus, she is sexually receptive for between seven to 10 days. After mating, she looks for a den in a cave in a rocky bluff, hollow tree, or a dense, preferably thorny, thicket. Gestation lasts 79 to 82 days, and usually results in the birth of a single kitten with closed eyes and a thin covering of hair. Litters of two or three kittens also occur, but are less common. The small litter size and relative infrequency of breeding make the ocelot particularly vulnerable to population loss.
Compared with other small cats, ocelot kittens grow quite slowly. They weigh around 250 grams (8.8 oz) at birth, and do not open their eyes for 15 to 18 days. They begin to leave the den at three months, but remain with their mother for up to two years, before dispersing to establish their own territory. Ocelots live for up to 20 years in captivity.
Ocelot Distribution and habitat
The ocelot is distributed extensively over South America (including the islands of Margarita and Trinidad), Central America, and Mexico with a small population in southern Texas. Countries in this range are: Argentina, Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname, Trinidad and Tobago, United States and Venezuela. The cat is likely extinct in Uruguay.
Ocelots only inhabit areas with relatively dense vegetation cover, although they may occasionally hunt in more open areas at night. They are found in tropical forest, thorn forest, mangrove swamps and savanna, at elevations ranging up to 1,200 meters (3,900 ft).
The ocelot once inhabited the chaparral thickets of the Gulf Coast of south and eastern Texas, and could be found in Arizona, Louisiana, and Arkansas. In the United States, it now ranges only in several small areas of dense thicket in South Texas and is rarely sighted in Arizona. On November 7, 2009, an ocelot was photographed in the mountains of Cochise County, Arizona. This was the first such verifiable evidence of the feline’s presence in the state. In February 2011, the Arizona Game and Fish Department confirmed the sighting of another ocelot in the Huachuca Mountains of southern Arizona. Most surviving Texas ocelots are in the shrublands remaining at or near the Laguna Atascosa National Wildlife Refuge near Brownsville, where only 30-35 animals remain.
The remnant U.S. ocelot population in south Texas has declined from 80-120 individuals in 1995 to less than 50 in recent years, with about half of ocelot deaths resulting from automobile accidents.
In Trinidad, habitat fragmentation, as well as direct exploitation via illegal poaching are major threats to the survival of the remnant populations of ocelots on the island. No empirical studies have been conducted to reliably estimate population status on the island. Historical records indicate that the species once existed on the island of Tobago, but it has long been extirpated there.
