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."

Wattled Crane
Bugeranus carunculatus
Wattled Crane
Bugeranus carunculatus
It is the largest crane in Africa. Both males and females have small white wattles on either side of their faces, although males' are slightly larger. They build nests in wetlands to lay eggs, with pairs taking turns incubating them. Chicks leave the nest in about 90 to 130 days. They are not migratory, and move depending on the amount of water in the wetlands. Their population is declining due to the loss of wetlands and human impacts.
