Bushbirds

species of bird

Clytoctantes is a South American genus of passerine birds in the antbird family, Thamnophilidae. They are medium sized, and males are grey or black and females are mainly rufous. The stubby, hefty bill has a distinctly upcurved lower mandible and a straight culmen (a large version of the bills of the recurvebills), which possibly is a modification for opening bamboo stems in their search for insects.
