Slaty Bristlefront: Its Place in Nature
The slaty bristlefront is very similar to another bird, Stresemann's bristlefront (Merulaxis stresemanni). Scientists think they might even be the same species! This bird does not have any different types or subspecies within its own group.
What Does the Slaty Bristlefront Look Like?
The slaty bristlefront is about 18.5 cm (7.3 in) long. That's about the length of a regular pencil!
- A male bird weighs around 37.2 g (1.31 oz).
- A female bird weighs about 33 g (1.2 oz).
Male and Female Differences
Male slaty bristlefronts are mostly dark blue-gray. Their lower back is dark brown. Their sides, belly, and tail are black.
Female slaty bristlefronts are different. They are mostly shades of brown. Their throat and chest are a lighter brown color.
Both male and female birds have a cool feature: a crest of short, stiff feathers. These feathers stand up straight at the base of their beak and on their forehead.
Where Do Slaty Bristlefronts Live?
You can only find the slaty bristlefront in southeastern Brazil. They live in a narrow strip of land near the Atlantic coast. This area stretches from the state of Espírito Santo down to Santa Catarina. They might have lived further north in southern Bahia a long time ago.
Their Forest Home
Slaty bristlefronts live in humid forests. These forests can be in lowlands or in mountains.
- Sometimes, you can find them as low as 100 m (330 ft) above sea level.
- More often, they live higher up, usually starting at 400 m (1,300 ft).
- In the northern parts of their home, they only live in the mountains. They can be found as high as 1,800 m (5,900 ft) there.
How Slaty Bristlefronts Behave
What Slaty Bristlefronts Eat
We don't know a lot about what slaty bristlefronts eat. They usually look for food in pairs. They search on the ground and in low plants. Even when they are in pairs, they don't stay very close to each other while foraging.
Reproduction and Nests
Only one slaty bristlefront nest has ever been described. It was found in the state of Rio de Janeiro.
- Both the male and female birds helped build the nest.
- They used small twigs, thin leaves, and leaf stems.
- The inside of the nest was lined with soft lichen.
- The nest was placed inside a burrow. This burrow was at least 1.24 m (4.1 ft) long. It was dug into an earthen bank.
Slaty Bristlefront Sounds
The slaty bristlefront has a unique song. It starts with a series of clicking sounds. Then, it makes a trill that sounds like "hysterical laughter."
They also have several different calls. Some of these calls are described as:
- “tsewk-tsewk, pit”
- “keekick”
- “he-he-heeheeheehee”
Protecting the Slaty Bristlefront
The IUCN (International Union for Conservation of Nature) has listed the slaty bristlefront as a species of "least concern." This means they are not in immediate danger of disappearing. However, they are still threatened by habitat loss. This is especially true in the lowland areas where they live.
