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."

How to use the beak
They can easily crack hard nuts using their large, powerful beaks, which they use as a third foot to bite branches and support their bodies when moving.
toes
Most birds have three toes in front and one in back, but macaws have two in front and two in back, forming an X. This shape is ideal for grasping food.
cry
They make very loud calls, which are important for communicating with members of their pack in the dimly lit forest. They also imitate the sounds of other individuals in the pack to communicate with others. Because of this characteristic, they sometimes imitate human speech.
Danger in the wild
The main threats to the decline in parrot and parakeet populations are thought to be agriculture, hunting, trapping, and deforestation. Red-and-green Macaw are unlikely to become extinct in the near future, but their populations are declining. Because they are popular as pets, they are listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), so continued attention must be paid to the trends in wild populations.
