White-bellied spinetail
The white-bellied spinetail is a species of bird in the family Furnariidae. It is found in river islands of the western Amazon Basin. Its natural habitat is subtropical or tropical moist shrubland.
This species was originally placed in the genus Synallaxis but when molecular phylogenetic studies found that it was not closely related to the other members of the genus it was moved to its own monotypic genus Mazaria.
