Hyenas or Hyaenas (from Greek "ὕαινα" - hýaina) are the animals of the family Hyaenidae (pron.: //) of suborder feliforms of the Carnivora. It is the fourth smallest biological family in the Carnivora (consisting of four species), and one of the smallest in the mammalia. Despite their low diversity, hyenas are unique and vital components to most African and some Asian ecosystems.
Although phylogenetically close to felines and viverrids, hyenas are behaviourally and morphologically similar to canines in several aspects (see Convergent evolution); both hyenas and canines are non-arboreal, cursorial hunters that catch prey with their teeth rather than claws. Both eat food quickly and may store it, and their calloused feet with large, blunt, non-retractable nails are adapted for running and making sharp turns. However, the hyenas' grooming, scent marking, defecating habits, mating and parental behaviour are consistent with the behaviour of other feliforms. Although long reputed to be cowardly scavengers, hyenas, especially spotted hyenas, kill as much as 95% of the food they eat, and have been known to drive off leopards or lionesses from their kills. Hyenas are primarily nocturnal animals, but may venture from their lairs in the early morning hours. With the exception of the highly social spotted hyena, hyenas are generally not gregarious animals, though they may live in family groups and congregate at kills.
Amboseli National Park, formerly Maasai Amboseli Game Reserve, is in Kajiado District, Rift Valley Province in Kenya. The park is 39,206 hectares (392 km2; 151 sq mi) in size at the core of an 8,000 square kilometres (3,100 sq mi) ecosystem that spreads across the Kenya-Tanzania border. The local people are mainly Maasai, but people from other parts of the country have settled there attracted by the successful tourist-driven economy and intensive agriculture along the system of swamps that makes this low-rainfall area (average 350 mm (14 in)) one of the best wildlife-viewing experiences in the world with 400 species of birds including water birds, pelicans, kingfishers, crakes, hammerkops and 47 types of raptor.
The park protects two of the five main swamps, and includes a dried-up Pleistocene lake and semi-arid vegetation.
140 kilometres (87 mi) South of the capital city Nairobi, Amboseli National Park is the second most popular national park in Kenya after Maasai Mara National Reserve and the visit can easily be done in a weekend.
