No.492 Oriental Reed Warbler Acrocephalus orientalis

L=18.5cm

Rank : 2
Summer Visitor
This species, who sings ket-ket-shi in reedbeds at the beginning of summer with its mouth wide open, is sometimes called ggyo-gyo-shihin Japanese. The first recognition of this species in the Asakawa River basin every year is between mid-April and the beginning of May. Since the bird stops singing and retreats to thickets after the breeding season, the time for leaving here for the south is not defined; however, we presume the time for migration to the south is from the latter half of September to the first half of October, based on our observation recorded on October 6.
