Eumyias thalassinus, commonly known as the Verditer Flycatcher, is a bird species found in parts of South and Southeast Asia.

This bird species is known for its distinctive appearance, featuring bright blue-green plumage on its upper body, with a paler blue-green on its head and a yellow-orange belly. They have a relatively small, straight bill and a short tail.

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

Verditer Flycatchers are known for their vocalizations, which include a variety of calls and songs. They are also appreciated by birdwatchers and nature enthusiasts for their striking coloration and unique behaviors, such as their habit of sallying out from perches to catch flying insects.

Verditer Flycatchers are 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 2-4 eggs, which are incubated for around two weeks.

Verditer Flycatchers 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.
