CONSERVATION STATUS

Least Concern

The Von Schrenck's Bittern has a large breeding range of 1,390,000 square kilometers. It breeds in reed marshes in southeastern Russia, Japan, the Korean peninsula, and eastern China. Most individuals of this species winter in wetland habitats in the Philippines and Indonesia, and, on rare occasion, in Palau. The global population for the Von Schrenck's Bittern is estimated at 1,000 to 25,000 individuals. Although this species is believed to be in decline because of habitat destruction, the population is still large enough to warrant a conservation rating of Least Concern.
