Mangrove Robins are just that, restricted to the coastal mangroves of northern Australia from Exmouth Gulf in W.A. around to near Proserpine in Queensland.This distribution is not continuous, but broken by the absence of suitable habitat, particularly the Eighty-mile Beach in W.A., but also in areas where the structure of the mangroves is not to their liking.

Mangrove Robins maintain permanent territories either as pairs or family groups. They spend most of their time either on or within a couple of metres of the ground feeding on insects or the odd small crustacean.
