Zoo Stock Species and the Red List
Zoo Stock Species and the Red List
Zoo Stock
This indicates that the species is included in the Second Zoo Stock Plan, which was formulated by the Tokyo Metropolitan Government in 2018. The plan sets goals for the next 10 years in three areas: "species conservation," "contribution to wildlife conservation," and "environmental education and conservation awareness." 124 animal species are included.
What is the Red List?
Based on scientific research, this is a list of wildlife classified by rank (category) indicating the degree of risk of extinction.
Livng Things Encyclopedia shows the categories (mainland and islands) assessed by the IUCN (International Union for Conservation of Nature) at the global level, the Ministry of the Environment for Japan, and the Tokyo Metropolitan Government for Tokyo.
The higher the category in each table, the higher the risk of extinction, and CR, EN, and VU are the three categories known as "endangered species." In Tokyo, species that are not at the NT (near threatened) level but are relatively rare are considered "species of concern."

African White-backed Vulture
Gyps africanus
African White-backed Vulture
Gyps africanus
It has a small amount of white down-like feathers on its head and a dark brown beak. When it spreads its wings, the white feathers on its back are clearly visible. It is a scavenger, feeding on the flesh of dead animals, and glides through the air with its wings spread in search of food. It is thought that the lack of feathers from its head to its neck is an advantage as it does not get dirty easily when eating carrion. It builds nests in trees and lays a single egg, but its population is declining due to habitat destruction and other factors.
