The White-bellied Heron is a critically endangered heron species found only in Bhutan, Northeast India, and Myanmar. Fewer than 60 confirmed White-bellied Herons exist in the world today. While there are few records of occurrence of the bird from the range countries, nests of this species have remained one of the rarest in history. Before 2000, only two nests had been found which were presumed to be of this bird; one was reported in Darjeeling, India, before 1890 and another in Myanmar, before 1930. With lack of breeding evidence, the bird was assumed to have vanished during late 1900 until a new nest was found in Bhutan in 2003. Since then, two to five active nests have been identified in Bhutan from where two to eight new chicks fledge annually. However, the population has remained critically low and the trend is further declining.
