Habitat & Fossil Locality

Small uninhabited rocky islands at sea (for breeding), nesting alongside Greater Crested Tern and Black-tailed Gull colonies

💡 Everyday Comparisons for Size, Mass & Speed

💡 Its wingspan of 94 cm is slightly more than half the arm span of an adult human (about 1.7 m) (Comparison).
💡 Its entire global population of about 150 birds is roughly the number of students in five school classes (assuming 30 students per class) (Comparison).

📖 1. Overview

The Chinese Crested Tern is a seabird that breeds only on small remote islands off the coast of China, Taiwan, and Korea; it is listed as Critically Endangered (CR) by the IUCN, with only about 150 individuals worldwide. Its population has been slowly increasing from fewer than 50 birds before 2012.

🦴 2. Anatomy & Morphology

Its body length is about 45 cm and its wingspan is 94 cm. It has a short crest, a black crown in the breeding season, and a bright orangish-yellow bill with a black tip.

🔍 3. Ecology & Behavior

When breeding, it often gathers inside Greater Crested Tern colonies and may move between different colony sites even within the breeding season. In Korea, it nests among Black-tailed Gull colonies on Chilsando.

🇰🇷 4. Connection to Korea

In Korea, it is a Class I endangered wildlife (Korea). In 2016, its first breeding outside China was confirmed on an uninhabited island off Jeonnam, and the East Asian-Australasian Flyway Partnership lists Chilsando as its breeding site in Korea.
