Leopardus pardalis

Geographic Range

Ocelots are most populous in Central America but can be found in all countries between southeastern United States (Texas, Arizona) and northern Argentina. They are found in higher density clusters in northern Central America, northwestern South America, northeastern South America, and central southern South America.

Habitat

Ocelots are found in a variety of habitats, including tropical forests, savannah grasslands, mangrove forests and marshes, and thorn scrub regions. They generally live at elevations below 1,200 m, but have been sighted at 3,800 m as well. Their primary habitat requirement is dense vegetative cover. Ocelots are found in open areas only when it's cloudy or at night when there is a new moon.

Physical Description

Ocelots are the largest member of the genus Leopardus . They weigh between 8.5 and 16 kg, are between 65 and 97 cm long, and males are considerably larger than females. Their pelage is shorter and less soft and thick than their close relative, the margay ( Leopardus wiedii ). Their ventral pelage is white and their dorsal pelage ranges from off-white to tawny-yellow to reddish-gray. Pelage coloration varies with habitat, as ocelots from arid scrub regions have grayer coats than those found in tropical forests. Entirely black individuals have been seen but are rare. Usually, ocelots have dark streaks, blotches, or rosettes arranged in small clusters around dark-colored areas that tend to run in parallel, horizontal chains. Rosettes and blotches are bordered with black and have a lighter-colored center. Ocelots have two black stripes on their cheeks, black ears with a central yellow spot, and one or two black transverse bars on the insides of the legs. Facial patterns are very distinct, permitting easy recognition of individuals. Their long tail is typically ringed, but may only be marked with dark bars on the dorsal surface. Relative to body-size, they have large paws, which is why their Spanish name is "manigordo", meaning big feet. Additionally, their fore paws are broader than their hind paws. Like other members of the suborder Feliformia , ocelots lack a third molar, have an absent or reduced postglenoid foramen at the base of the skulls, and an anterior palatine canal that passes through the maxilla. They have a concave muzzle and the dental formula is 3/3, 1/1, 3/2, 1/1 for a total of 30 teeth. Their basal metabolic rate is approximately 0.298 cm^3 oxygen/hour.

Reproduction

Ocelots are solitary and polygynous, with a single male home range overlapping those of several females. During estrus, females attract potential mates by making loud yowls, similar to those made by domestic cats ( Felis catus ). After mating pairs are formed, ocelots copulate between 5 and 10 times daily. The likelihood of conception per estrus, which lasts approximately 5 days, is 0.6.

Ocelots are year-round breeders in the tropics, but autumn and winter birthing peaks reportedly occur in the northern parts of their range (e.g., Mexico and Texas). Estrus lasts 4.63 days on average, and their estrus cycle lasts 25.11 days on average. Once pregnant, females create a den in thick brush where parturition occurs. Gestation lasts 79 to 85 days, and litter sizes range from 1 to 3 kittens, with an average of 1.63 kittens/litter. Young weigh between 200 and 340 g at birth. Females are thought to have 1 litter every 2 years.

Ocelots are weaned by 6 weeks old and reach adult size at about 8 to 10 months old. Females reach sexual maturity at 18 to 22 months old and may breed until they are 13 years old. Males may become sexually mature as early as 15 months; however, spermatogenesis typically begins around 30 months. Evidence suggests that sexual maturation in males is related to territory acquisition.

Females alone provide parental care to their young. Juvenile ocelots are weaned by 6 weeks old and begin to observe their mother during hunts a few months after birth. They are independent at approximately 1 year, but may be tolerated in their mother's home range until about 2 years old. After dispersing, juveniles must find their own territories.

Lifespan/Longevity

In the wild, ocelots live between 7 and 10 years. The oldest known captive ocelot lived to be 21.5 years old in the Phoenix Zoo.

Behavior

Like many cats, Leopardus pardalis is solitary. It generally travels alone, but may form loose associations with conspecifics in adjacent territories. It communicates by mewing and attracts potential mates via yowling. Leopardus pardalis , which is nocturnal and crepuscular, can be found sleeping during the day, likely in hollow trees, amidst thick vegetation, or on branches. Although terrestrial, L. pardalis is also adept at climbing, jumping, and swimming. It is active for over 12 hours/day, during which time it can travel between 1.8 and 6.7 km, with males traveling nearly twice as far as females.

Home Range

Ocelots are highly territorial. Their home ranges are between 2 and 31 km^2, depending on habitat. Male ranges are larger than females and do not over lap with those of other males. However, as in many other mammalian species male ranges tend to overlap with those of several females. Population densities average 4 individuals per every 5 km^2 in lowland tropical forests and 2 to 5 individuals per every 5 km^2 in more open regions, including nonbreeding transients.

Communication and Perception

Leopardus pardalis has keen senses of smell and vision. It uses its sense of smell to locate, track, and approach prey as well as to determine territorial boundaries. They have acute binocular vision that is well-developed for hunting at night. Leopardus pardalis communicates with conspecifics using chemical signals to demarcate territorial boundaries and vocalizations (e.g., mews and yowls) to attract and communicate with potential mates.

Food Habits

Ocelots are highly skilled hunters, tracking prey by odor trails, and have an average of 0.9 prey captures per kilometer traveled. Once a prey item is captured, they eat at the kill site and cover the remains when they are finished. Similar to other felids, ocelots are well-adapted to their carnivorous diet, shearing ingested tissue from carcasses with their carnassials, while depending on strong digestive enzymes to help break down ingested proteins.

The diet of ocelots consists of 65 to 66% small rodents, 12 to 18% reptiles, 6 to 10% medium-sized mammals, 4 to 11% birds, and 2 to 7% crustaceans and fish. Their primary prey consists of nocturnal species, including cane mice ( Zygodontomys ), spiny rats ( Echimyidae ), common agoutis ( Dasyprocta ), opossums ( Didelphimorphia ), and armadillos ( Cingulata ). Although most prey weighs less than 1 to 3% of their body weight, ocelots also take larger prey, including lesser anteaters ( Tamandua tetradactyla ), red brocket deer Mazama americana , squirrel monkeys ( Saimiri sciureus ), and land tortoises ( Testudinidae ).

Predation

Although predators themselves, ocelots occasionally become the prey of harpy eagles ( Harpia harpyja ), pumas ( Puma concolor ), jaguars ( Panthera onca ), and anacondas ( Eunectes murinus ). Many of the characteristics that make them great predators may be useful as antipredator defense mechanisms (e.g., camouflage, keen senses, etc.).

• Anti-predator Adaptations
• cryptic cryptic

Ecosystem Roles

Ocelots significantly impact their environment as predators. Although they feed primarily on terrestrial vertebrates, ocelots are opportunistic hunters and prey upon many types of animals. Occasionally, they serve as prey for larger carnivores (e.g., jaguar, Panthera onca ) and are host to numerous parasites.

Economic Importance for Humans: Positive

From the early 1960's to the mid 1980's, there was high demand for spotted-cat furs in Western society. During this time, a coat made of ocelot fur could sell for $40,000 (U.S.) in western Germany. Ocelots were also popular as exotic pets, costing as much as $800 per individual. After the 1975 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the international trade of ocelots and their by-products (e.g., fur) became illegal in most countries. However, one can still buy such items at the Managua International Airport in Nicaragua or illegally on the black market.

Ocelots may be beneficial to humans by controlling rodent populations that could be considered agricultural pests.

• Positive Impacts
• pet trade pet trade
• body parts are source of valuable material
• controls pest population

Economic Importance for Humans: Negative

In regions where natural prey abundances have been significantly reduced, ocelots may kill and eat domestic fowl.

Conservation Status

Due to their abundance and broad distribution, ocelots are list as a species of "least concern" according to the IUCN Red List of Threatened Species. Major threats to their persistence include habitat loss and fragmentation, illegal trade as pets and pelts, and retaliatory killings by poultry farmers. Despite this, ocelots have made a strong recovery and it was estimated that there were between 1.5 and 3 million ocelots living in 1996.

Due to their popularity in Western fur trade, ocelots were nearly extinct by the mid 1980's. Concern over their potential extinction contributed to the formation of the 1975 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The selling of ocelot fur significantly decreased in the 1980's and is no longer considered a threat to their survival.

Once found as far east as Louisiana and Arkansas and now found only in southernmost Texas, Leopardus pardalis albescens is the only subspecies that is classified as endangered. This subspecies' declining numbers are likely the result of habitat loss, which is forcing individuals to have larger home ranges in order to support their daily prey requirements. However, larger home ranges may decrease mating opportunities.

Other Comments

Leopardus pardalis has multiple common names throughout its range, including "gato maracaja" in Brazil and Paraguay, "gato onza" in Argentina, Bolivia, and Peru, and "manigordo" in Costa Rica, Nicaragua, Panama, and Venezuela.
