Zoo Stock Species and the Red List

Zoo Stock

dummy

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."

This color resembles the legendary creature "Shojo," hence the name. It searches for food by pecking at the roots of mangroves and the banks of lakes and ponds with its long, downward-curving beak, eating hermit crabs and other creatures.

Chick appearance

Scarlet Ibis chicks

Newly hatched chicks look different from adult birds. Their entire body feathers are black, making them less noticeable in the nest. Even when they have grown large enough to leave the nest, their coloring is still different from that of adult birds, and after about two years they will turn the same crimson red as adult birds. Their beaks are also short and straight, and as they grow, they will elongate and then curve again.
