Little Egret コサギ Scientific name: Egretta garzetta The Little Egret is a small, elegant white heron commonly seen around Japan’s rivers, rice fields, ponds, tidal flats, and wetlands. In Japanese it is called コサギ / Kosagi, meaning “small egret.” It has a slim white body, long black legs, black bill, and bright yellow feet. The yellow feet are one of the best identification points, especially when comparing it with larger white egrets. During the breeding season, it develops beautiful thin ornamental plumes on the head, chest, and back. In Japan, the Little Egret is usually seen walking slowly in shallow water, then quickly striking at fish, shrimp, frogs, insects, and other small aquatic animals. It may also stir the water with its bright yellow feet to flush prey. Habitat: Rivers, rice fields, ponds, marshes, lakes, estuaries, tidal flats, coastal shallows Range in Japan: Widespread in suitable wetland habitats, especially central and southern Japan Diet: Small fish, shrimp, frogs, aquatic insects, crustaceans, and small animals Season: Year-round in many warmer areas; more seasonal in northern regions Size: About 55–65 cm Nesting: Nests colonially in trees, often with other herons and egrets Behavior: Walks actively in shallow water; may use yellow feet to disturb prey Conservation: Common and widespread, but healthy wetlands, rivers, and rice-field environments are important.

It hunts by walking through shallow water and striking quickly at small fish, shrimp, frogs, and insects. The コサギ is one of Japan’s most elegant and familiar waterside birds.
