LEOPARDUS TIGRINUS PDF

Le rosette sono nere o marroni, chiare al centro, e di forma irregolare [6]. Questa colorazione aiuta il gatto tigre a mimetizzarsi tra le macchie di luce che filtrano attraverso la densa vegetazione della foresta tropicale. Mangia piccoli mammiferi, lucertole, uccelli, uova, invertebrati, e di rado rane degli alberi. Il gatto tigre avvista la sua preda da lontano e, una volta a tiro, balza sulla vittima per catturarla e ucciderla [6] [7]. I cuccioli sono stati osservati fare le fusa, e gli adulti sono conosciuti per i brevi gorgoglii di richiamo quando si avvicinano gli uni agli altri [4]. Partoriscono da uno a 3 cuccioli di solito uno dopo una gestazione di giorni [8].

Characteristics[ edit ] The oncilla resembles the margay and the ocelot , [4] but it is smaller, with a slender build and narrower muzzle. The underside is pale with dark spots and the tail is ringed. The backs of the ears are black with bold white spots. The rosettes are black or brown, open in the center, and irregularly shaped. The legs have medium-sized spots tapering to smaller spots near the paws.

This coloration helps the oncilla blend in with the mottled sunlight of the tropical forest understory. Like all cats, the oncilla is an obligate carnivore, requiring meat for survival. This cat eats small mammals, lizards, birds, eggs, invertebrates, and the occasional tree frog. Occasionally, the cat will eat grasses. The oncilla stalks its prey from a distance, and once in range, it pounces to catch and kill the prey.

Young oncillas have been observed to purr, while adults are known to make short, gurgling calls when close to one another. Unlike other cats, in which the incisor teeth tend to appear first, the teeth of an oncilla kitten erupt more or less simultaneously, at around 21 days of age.

They have a life span of about 11 years in the wild, but there are records of these cats reaching an age of 17 years. Researchers have argued that there should be a splitting of the oncilla into two species, as there is a pronounced difference in appearance between the oncillas in Costa Rica and those in central and southern Brazil. The level of divergence between oncillas from Costa Rica and from central and southern Brazil suggests that the two populations have been isolated, perhaps by the Amazon River, for approximately 3.

Based on these results, the eastern group was proposed to be a distinct species Leopardus emiliae. It is mainly threatened by deforestation and poaching. Oncillas are killed for their pelts, which are highly prized and often sold or made into clothing. Coffee plantations are most often established in cloud forest habitats, causing the reduction of preferred habitats.

Such hybridization may be a natural process, and the extent of this as a threat to the oncilla is unknown. In captivity, the oncilla tends to have high infant mortality rate.
