The Mangrove Robin is a grey robin known from coastal forests of New Guinea and northern Australia. A study in Australia's Northern Territory also reported a breeding population in wetland vegetation away from mangroves.
A regional bird guide describes a small grey robin with a white throat and a black tail whose outer feathers are white.
At Arafura Swamp, one population foraged through leaf litter on dry ground and ate insect larvae. A recently fledged young bird was recorded there in October 2016.
