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."

Creatures at Tama Zoo

Puna Ibis
Plegadis ridgwayi

Even among Crested Ibis family, it has a small body and a slightly shorter beak. A similar-coloured bird is Northern Bald Ibis, but unlike Northern Bald Ibis, Puna Ibis is small and its head is not exposed. It is covered in shiny black feathers, which is where the name "bronze" comes from. Due to structural colouring, these feathers can appear shiny purple or green depending on the angle of observation and the sunlight.

classification	Birds, Pelecaniformes, Crested Ibis
English name	Puna Ibis
distribution	From the central highlands of Peru to southern Bolivia, northernmost Chile, and northwestern Argentina
Residence	Wetlands, meadows, tidal flats, ponds, streams, as well as marshes and swamps at altitudes of 3,500-4,800 m.
Size	Total length: 56-61cm
food	Arthropods and invertebrates
Red List	IUCN: LC (Least Concern)

Foraging behavior

They feed in wetlands and other waterside areas. Their long, slender, downward-curving beak has a sensitive tip with a concentration of nerves. They peck at the ground with this beak to find insects, crustaceans, and other creatures.
