Habitat & Geographic Range

Cheetah

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 9 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Botswana, Iran, Kenya, Namibia, and Tanzania. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Christmas Island Imperial-Pigeon

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Found in Norway.

Cheetah

The fastest land animal on Earth, reaching speeds of 112 km/h over short distances across African and Iranian grasslands. Slender build with a deep chest, long legs, and distinctive black tear-stripe markings. Unlike other big cats, cheetahs vocalize with chirps and purrs. Vulnerable, with only ~7,000 remaining due to habitat fragmentation and competition with larger predators.

Christmas Island Imperial-Pigeon

The Christmas Island imperial pigeon (Ducula whartoni) is a large frugivorous pigeon in the family Columbidae, endemic to Christmas Island, an Australian territory in the Indian Ocean. It is one of several vertebrate species unique to Christmas Island, reflecting the island's isolation and the evolutionary divergence of its fauna over millions of years. Like other members of the genus Ducula, the imperial pigeons, it is a substantial bird and an important seed disperser within the island's rainforest ecosystem. The species feeds primarily on forest fruits and plays a keystone ecological role in moving seeds of large-fruited trees across the island. Imperial pigeons in this group are often characterized by pale gray and iridescent plumage. The Christmas Island imperial pigeon inhabits the dense tropical rainforest that covers much of the island's interior plateau. Conservation threats include habitat loss from past phosphate mining operations and the ongoing impacts of invasive species, particularly the yellow crazy ant, which has dramatically altered forest ecology through the farming of scale insects, leading to canopy dieback over large areas. The species' restricted range and dependence on intact forest make it susceptible to further habitat deterioration. Active conservation management on Christmas Island includes invasive species control programs.
