The Malayan night heron (Gorsachius melanolophus), also known as Malaysian night heron and tiger bittern,is a medium-sized heron. It is distributed in southern and eastern Asia.br br Males develop the dark blue lores 30–60 days prior to pair-bonding, while females had bluish-green lores when they first appeared in the breeding areas. Colours of the lores of both sexes faded as incubation progressed, with colours changing to bluish-green to green to greyish-green. If pairs laid a second clutch, the colouration of their lores were duller than the colouration during the first clutch.
