What Does It Look Like?
The tooth-billed wren is about 12 cm (4.7 in) long. One male bird weighed about 11 g (0.39 oz). Adult wrens have a grayish cinnamon color on their head. Their face is grayish brown. Their back is a medium gray.
Their throat and chest are a buffy gray color. The belly is a pale buff. The sides of their body are grayish white. Young wrens look very similar to the adults.
Where Does It Live?
The tooth-billed wren lives mostly in Brazil. Its home range also reaches a little into Bolivia's Santa Cruz Department. You can find it south of the Amazon River. It lives between the Madeira River in the west and the Xingú River in the east.
This bird likes to live in tall, wet lowland forests. It can be found in areas up to 600 m (2,000 ft) high.
How It Behaves
What It Eats
We don't know all the details about what the tooth-billed wren eats. But we do know it eats insects. It looks for food high up in the trees. This is called the canopy. It searches about 15 to 30 m (49 to 98 ft) above the ground.
It explores leaves and vines on branches. It often joins groups of different bird species looking for food together. This is called a mixed-species foraging flock.
Reproduction and Life Cycle
The tooth-billed wren's breeding season seems to be from June to September. This is based on when active nests and young birds were seen. They build their nests in a hole in a tree branch or trunk. These nests are usually high above the ground. It is thought that they lay two eggs at a time.
Its Voice
The tooth-billed wren's usual song is a short, simple trill [1]. Both male and female wrens sing this song.
Is It Safe?
The IUCN (International Union for Conservation of Nature) has said the tooth-billed wren is of "Least Concern." This means it is not currently in danger of disappearing. However, the number of these birds has not been counted exactly. Experts think their population might drop by almost 30% over three generations.
