Lion
VulnerableWhat is a lion? The lion (Panthera leo) is a large, warm-blooded mammal belonging to the Felidae family. Widely referred to as the 'King of the Jungle', the lion is a majestic big cat that plays a key role as an apex predator in its ecosystem. Unlike other cats, lions are highly social animals that live in family groups called prides. A pride typically consists of related females, their offspring, and a small coalition of male lions who protect the territory. Male lions are famous for their majestic manes, which darken as they age and serve as a sign of health and dominance.
Mammals
Cheetah
VulnerableThe cheetah is the fastest land animal on Earth, built for speed and agility. Its slender, lightweight body, long legs, and flexible spine allow it to take strides of up to 7 meters. Cheetahs have distinct black 'tear marks' running from the inside corners of their eyes down to their mouth, which help deflect the blinding glare of the sun during daytime hunting. Unlike other big cats, cheetahs cannot roar, but they do purr, hiss, and make chirping sounds.
Birds (Aves)
Bald Eagle
Least ConcernThe bald eagle is a majestic bird of prey and the national bird of the United States. Easily recognized by its snowy-white head and tail, dark brown body, and bright yellow beak and feet, it is a powerful flyer. Bald eagles are expert fishers, swooping down to snatch fish from the water's surface with their sharp talons. They build the largest nests of any North American bird, which can reach up to 4 meters deep and 2.5 meters wide.
