佐渡島におけるミゾゴイの営巣初記録と生息状況

抄録

I observed a nest of the Japanese Night Heron Gorsachius goisagi in Sado Island, Niigata Prefecture on 20 July 2014. This is the first breeding record of this species from the island. There have been some observation records of the species in recent breeding seasons in the island. It suggests that some pairs of the herons breed in the island.
