The species is confined to an area of about 5 km² with some wooded areas, isolated from the rest of the forested areas to the west of the peninsula by the presence of agricultural land which prevents extension of the species’ habitat.
Cutting of nesting vegetation:
Caravelle peninsula fishermen use cage-traps that they make on-site using small branches cut from the natural habitat and in a protected area. Other than the fact that this is forbidden, the branches are used as a support for the birds nest.
Invasive alien species :
The Black rat and Small Indian mongoose, both introduced by man, are both important predators of the White-breasted thrasher. Other species such as feral cats and Common opposums are also an important threat.
