Von Schrenck's bittern

Von Schrenck's bittern (Ixobrychus eurhythmus), also known as Schrenck's bittern, is a small bittern. It breeds in China and Siberia from March to July, and Japan from May to August. It winters in Indonesia, Philippines, Singapore, Laos, passing through the rest of South-east Asia. It is an exceptionally rare vagrant as far west as Europe, with a single sighting in Italy in 1912. It is named after Leopold von Schrenck, the 19th-century Russiannaturalist.
