Megalaima virens, commonly known as the Great Barbet, is a bird species found in parts of South and Southeast Asia.

This bird species is known for its distinctive appearance, featuring a large head and a thick, curved bill. They have bright green plumage on their upper body, with a yellow lower belly and a red patch on their face. They also have a black stripe running from their bill to their eyes.

Great Barbets are native to parts of South and Southeast Asia, including India, Nepal, Bhutan, Bangladesh, Myanmar, Thailand, Laos, Cambodia, and Vietnam. They are typically found in forested habitats, particularly in mountainous areas. They feed on a diet of fruits and insects.

Great Barbets are known for their loud, distinctive calls, which can be heard from a long distance away. They are also appreciated by birdwatchers and nature enthusiasts for their striking coloration and unique behaviors, such as their habit of excavating holes in trees to build their nests.

Great Barbets are generally monogamous and form pairs during the breeding season. They build nests in tree cavities or other suitable locations, using plant fibers and other materials. The females typically lay 2-3 eggs, which are incubated for around two weeks.

Great Barbets are not considered to be globally threatened at this time, although they are threatened by habitat loss and degradation due to deforestation and other human activities. Conservation efforts are needed to protect their populations and their forest habitat, including the establishment of protected areas and sustainable forest management practices.
