Black-bibbed Monarch Symposiachrus mundus

A gray-and-white flycatcher-like songbird confined to the eastern Lesser Sundas. Head slate-gray with well-defined black mask and throat. Underparts bright white and upperparts slate-gray, with dark tail displaying obvious white outer feathers. Juveniles are grayish-brown above and cinnamon below, with white on face, throat, and neck. Singles and pairs frequent mixed-species flocks within understory of forest, forest edge, and mangroves. Lacks orange on breast, unlike Spectacled Monarch. Song is a high-pitched, descending whistled “seeeer.” Also gives a scratchy “k’schrrrr,” “schrrrr,” and rasping “weeee.”
