Discover the Ant Thrush species Chamaeza found in a highland rainforest in northeastern Brazil.
“Chamaeza consists of terrestrial subterranean birds specialized for life in the understory of Neotropical forests,” said ornithologist Wagner Cavalzere of Paulista University and his colleagues.
“These secretive birds inhabit forest floors from lowlands to mid-altitude mountains, where they primarily forage for arthropods in leaf litter and among fallen trees.”
“They may chase swarms of army ants, but this behavior is less frequent than other ant-chasing birds.”
“Chamaeza species display cryptic plumage suitable for leaf litter camouflage and have no apparent sexual dimorphism.”
“Their reproductive strategy requires nesting in natural cavities in decaying logs and biparental care from chick to fledging stage.”
“Ecologically, they are solitary foragers with limited dispersal ability, reflecting their specialization within stable forest interiors.”
“This genus consists of six species with a distinct biogeographical distribution throughout the forested regions of South America.”
In a new study, the authors Giant Ant Thrush (Chamaeza Campanisona) have identified new species Chamaeza baturitensis, also known as Baturite Thrush.
“Currently, there are 12 subspecies of Chamaeza Campanisona found in northern and central South America,” they explained.
The researchers analyzed 183 audio recordings of the subspecies, revealing distinct song patterns in different populations.
Morphological differences were also observed in the new species, including a lack of a small black spot on the beak found in southern populations.
“Chamaeza baturitensis is known to inhabit a rainforest enclave in northeastern Brazil and is under threat from poaching,” the scientists noted.
Further research is needed to assess the conservation status of this newly discovered species.
The discovery of Chamaeza baturitensis is detailed in a paper published in a zoo magazine.
