Florida panther
Subspecies of cougar endemic to Florida

For the hockey team, see Florida Panthers. For other uses, see Florida panther (disambiguation).
The Florida panther is a North American cougar (P. c. couguar) population in South Florida. It lives in pinelands, tropical hardwood hammocks, and mixed freshwater swamp forests. It is known under a number of common names including Costa Rican puma, Florida cougar, and Florida puma.

Quick Facts Conservation status, Scientific classification ...
Males can weigh up to 73 kg (161 lb) and live within a range that includes the Big Cypress National Preserve, Everglades National Park, the Florida Panther National Wildlife Refuge, Picayune Strand State Forest, rural communities of Collier County, Florida, Hendry County, Florida, Lee County, Florida, Miami-Dade County, Florida, and Monroe County, Florida. It is the only confirmed cougar population in the eastern United States, and currently occupies 5% of its historic range. In the 1970s, an estimated 20 Florida panthers remained in the wild, but their numbers had increased to an estimated 230 by 2017.

In 1982, the Florida panther was chosen as the Florida state animal.

Description
Florida panthers are spotted at birth, and typically have blue eyes. As the panther grows, the spots fade and the coat becomes completely tan, while the eyes typically take on a yellow hue. The panther's underbelly is a creamy white, and it has black tips on the tail and ears. Florida panthers lack the ability to roar, and instead make distinct sounds that include whistles, chirps, growls, hisses, and purrs. Florida panthers are average-sized for the species, being smaller than cougars from colder climates, but larger than cougars from the Neotropics. Adult female Florida panthers weigh 29–45.5 kg (64–100 lb), whereas the larger males weigh 45.5–72 kg (100–159 lb). Total length is from 1.8 to 2.2 m (5.9 to 7.2 ft) and shoulder height is 60–70 cm (24–28 in). Male panthers, on average, are 9.4% longer and 33.2% heavier than females because males grow at a faster rate than females and for a longer time.

Taxonomic status
It was described as a distinct cougar subspecies (Puma concolor coryi) in the late 19th century. The Florida panther had for a long time been considered a unique cougar subspecies, with the scientific name Felis concolor coryi proposed by Outram Bangs in 1899. A genetic study of cougar mitochondrial DNA showed that many of the purported cougar subspecies described in the 19th century are too similar to be recognized as distinct. It was reclassified and subsumed to the North American cougar (P. c. couguar) in 2005. Despite these findings, it was still referred to as a distinct subspecies P. c. coryi in 2006.

In 2017, the Cat Classification Taskforce of the Cat Specialist Group revised the taxonomy of Felidae, and now recognises all cougar populations in North America as P. c. couguar.

Diet
The Florida panther is a large carnivore whose diet consists both of small animals, such as raccoons, armadillos, nutrias, hares, mice, and waterfowl, and larger prey such as storks, white-tailed deer, feral pigs, and small American alligators. The Florida panther is an opportunistic hunter, and has been known to prey on livestock and domesticated animals, including cattle, goats, horses, pigs, sheep, chickens, dogs, and cats. When hunting, panthers shift their hunting environment based on where the prey base is. Female panthers frequently shift both their home range and movement behavior due to their reproductive rates.

Early life
A juvenile
Panther kittens are born in dens created by their mothers, often in dense scrub. The dens are chosen based on a variety of factors, including prey availability, and have been observed in a range of habitats. Kittens will spend the first 6–8 weeks of life in those dens, dependent on their mother. In the first 2–3 weeks, the mother spends most of her time nursing the kittens; after this period, she spends more time away from the den, to wean the kittens and to hunt prey to bring to the den. Once they are old enough to leave the den, they hunt in the company of their mother. Male panthers are not encountered frequently during this time, as female and male panthers generally avoid each other outside of breeding. Kittens are usually 2 months old when they begin hunting with their mothers, and 2 years old when they begin to hunt and live on their own.

Threats
Humans threaten the Florida panther through poaching and wildlife control measures. Besides predation, the biggest threat to the Florida panther is habitat fragmentation. It was persecuted, and the population reduced to a small area in southern Florida. The population became inbred with individuals having kinked tails, and heart and sperm problems.
