📖 1. Overview
Nordmann's Greenshank is a sandpiper that breeds along the Sea of Okhotsk coast and on Sakhalin and winters on tidal mudflats in Myanmar, Thailand, the Malay Peninsula, western Indonesia, and Bangladesh. It is listed as Endangered (EN) by the IUCN, with only 600–1,300 individuals worldwide.
🦴 2. Anatomy & Morphology
Its body length is 28–34 cm; compared with the Common Greenshank, its body tilts further forward, its bill is longer and blunter, and its legs are shorter.
🔍 3. Ecology & Behavior
It runs quickly to catch small crabs and small fish. Its numbers are declining as coastal development reduces tidal mudflats.
🇰🇷 4. Connection to Korea
In Korea, it is protected as a Class I endangered wildlife (Korea). The Hong Kong Bird Watching Society notes that it migrates along coastal wetlands in East Asia.
