The Eurasian bittern is a bulky heron with buff-and-brown streaked plumage that disappears among reeds. When alarmed it points its bill upward and sways with surrounding stems. It inhabits extensive reedbeds across Europe, North Africa and Asia, stalking fish, frogs, insects and small mammals. Males advertise with a deep booming call that carries across marshes (Wikipedia, general species account). It is Nationally Least Concern (Thailand Red Data 2025).
