Rondônia Bushbird
Encyclopedia
The Rondônia Bushbird is a bird
species
in the family
Thamnophilidae. It is endemic to Brazil
.
Males are blackish and females are mainly rufous
. The stubby, hefty bill has a distinctively upcurved lower mandible and a straight culmen.
Very little is known about this species. Its natural habitat
appears to be denser sections of tropical moist lowland forest
.
It was formerly classified as Critically Endangered
by the IUCN. All suitable habitat has been cleared from the locality where it was discovered in 1986, and many feared it was extinct, until it was discovered at another site in south-eastern Amazonas in 2004. Following the initial rediscovery, it has been located at yet another site in south-eastern Amazonas and a site in Rondônia
.
These sightings combined with an old record near Alta Floresta
considered likely but unconfirmed indicate it is more widespread than previously believed. It was consequently suggested that downlisting it to Vulnerable
status may be appropriate, and this was done in 2008.
