Von Schrenck's bittern or Schrenck's bittern (Ixobrychus eurhythmus ) is a small bittern (birds of the subfamily Botaurinae). It is named after Leopold von Schrenck, the 19th-century Russian naturalist.
The male is uniformly chestnut above, and buff below and on the wing covert feathers. The female and juvenile are chestnut all over with white speckles above, and white streaks below. When in flight, it shows black flight feathers and tail. It is a small species at 33 to 38 cm (13 to 15 in) in length, with a short neck, longish yellow beak and yellow legs.
It breeds in China and Siberia from March to July, and Japan from May to August. It winters in Indonesia, the Philippines, Singapore, Laos, passing through the rest of Southeast Asia. It is an exceptionally rare vagrant as far west as Europe, with a single sighting in Italy in 1912.
Von Schrenck's bittern breeds in reed beds and tends to emerge at dusk to forage for prey.
