Milky Stork

Scientific Name: Mycteria cinerea
Malay Name: Upih Bakau
Chinese Name: 白鹮鹳

Breeds in Cambodia, Thailand, and western Sumatra.


Size: 95-100 cm

Only similar species recorded locally is Painted Stork, with which this species interbreeds extensively. Differentiated from Painted by three main traits, which must all be present in combination: a clean white breast (Painted has a black breast-band); no pink flush on the tertials, inner secondaries, and wing-coverts; and clean white upperwing-coverts (Painted has black-and-white spotting on the upperwing-coverts). Individuals which lack any of these features cannot be identified as pure Milky Storks.

Similar looking species: Painted Stork

Habitat: Mangroves, mudflats, and coasts.

Local Status: Common introduced resident

Conservation Status: Endangered (BirdLife International 2016)
