The white-browed tit-warbler is a bird that lives in China, the Tian Shan, and the Himalayas, and can be found in boreal forests.
These birds are not only beautiful, but they’re also very polite as their tweets make the sound, “sirrrrrr.” The white-browed tit-warblers live in pairs during the breeding season, but around its end, they join flocks of 25 or more.
Fortunately, these colorful birds are not threatened by extinction, which could be due to their well-camouflaged nests or the lack of local predators.
