Males have a tougher time, but if they survive to five or six years old, they are likely to live even longer to 10 or more years. The two most common causes of panther deaths are vehicle collisions and panthers killing other panthers intraspecific aggression. Males also have killed females, and younger males have killed older males. Other causes of death among panthers include feline leukemia, illegal shootings, bacterial infections, rabies and pseudorabies.
Figure 1. Concurrent with increasing panther population numbers, the number of Florida panthers killed by collisions with vehicles has been on the increase since Prior to , panther roadkills were four or fewer a year, but beginning in , these numbers have ranged from six to 34 annually.
Figure 2. Number of Panther Roadkills As panther numbers increased over time, the number of panther roadkills have also been on the rise. Since , the number of roadkills has ranged from 6 to 34 annually. Figure 3. All Panther Roadkills by Sex The pie chart to the right shows the number of all panther roadkills by sex. More male panthers are killed in vehicle collisions than female panthers.
Males have larger home ranges than females, and their ranges often include roads. Young male panthers searching for their own ranges often end up crossing roads more frequently than adult panthers. This places them at a greater risk of colliding with a vehicle. Panthers less than 3 years old represent 70 percent of all roadkills; 22 percent of these deaths were kittens young enough to still be with their mother.
Figure 4. Ages years of panthers killed by vehicle collisions from The pie chart to the left shows the ages of panthers killed by vehicle collisions from Most panthers killed in vehicle collisions are three years of age or less. Female panthers reach sexual maturity at about one and a half to two and a half years old, and males at about three years old.
Panthers are polygamous, meaning they may mate with more than one partner. Males will try to prevent other males from mating with females within their ranges but they are not always successful. Mating pairs may remain together for up to a week, sleeping and hunting together. Panthers, like all other cats with the possible exception of lions, are induced ovulators. This means the stimulus of copulation triggers the release of the egg by the ovary. Induced ovulation is an adaptation for solitary cats to increase the probability that the egg will be fertilized.
Watch this short video to see how panthers communicate and find mates. A female panther will signify her sexual availability by the scent of her urine and through vocalizations like yowling that some people say sounds like a female human screaming.
The gestation period for panther kittens is 92 to 96 days, and litters consist of one to four kittens. Births can occur at any time of year but are most common between March and July. This means that they have fur, are born live, and drink milk when they are babies.
It also means that they are warm-blooded. Warm-blooded animals are able to regulate their internal body temperature. This means that no matter what kind of a climate they live in, their internal temperature will always be the same. Panther is not exactly different to the Leopard or the Jaguar. The term panther has been used to describe three different kinds of big cats. These include leopards , jaguars, and cougars. The largest of these three is the African Leopard. From head to tail, the Panther measures feet and weighs pounds.
Its hue ranges from dark brown to black. Panthers have black, gleaming fur coats on their lengthy bodies and tails. Their heads are pretty small, their jaws are robust and strong, their ears are rounded, their eyes are emerald green, and their legs are muscular.
Panthers are mostly dark brown or black in color. Though panthers look like an entirely new species of large cat, they are actually just leopards or jaguars that have a black color mutation which turns their normally golden fur black to match their spots. This mutation is known as melanism.
It does not happen very often and is in fact quite rare. Although they are solitary animals and do not live in families, leopards nevertheless have strong maternal bonds.
Even though the young become independent at about 22 months, the mother may continue to share kills with her offspring until they become totally self-sufficient.
The leopard is classically feline in its hunting behavior, specializing in stalking and ambushing its prey. A kill is usually dragged away from other predators and often stored in trees out of the reach of lions and hyenas. Leopards are renowned for their great strength and can haul a carcass greater than their own weight up the trunk of a tree. The muscles attached to the scapula are exceptionally strong, which enhance their ability to climb trees.
This great strength means a big adult leopard is capable of killing prey up to 10 times its own weight. Feeding on a greater diversity of prey than other members of the Panthera species, leopards will eat any warm-blooded prey, from mice and hares to large antelope. But a leopard is the supreme opportunist and will also eat birds, reptiles, rodents, and even insects. They select their prey focusing on small herds, dense habitat, and low risk of injury.
All leopard subspecies are either endangered or threatened. Leopard-skin coats were legal for many years and are still sold secretly. Many trees in leopard habitats have been cut down for building projects. And poachers are still killing leopards for their whiskers. In addition, because leopards prey on livestock, they are frequently poisoned by ranchers trying to protect their animals.
