Visitors to Taiwan’s forests will be very familiar with the Morrison’s Fulvetta, which is among the commonest passerines on the island, and often the core component of roaming mixed-species understory flocks. It is a small, seemingly permanently active songbird, with brown upperparts, buff underparts, a predominantly gray head, large white eye-ring, and narrow, difficult-to-discern black lateral crown-stripes. This species, along with the Yunnan Fulvetta (Alcippe fratercula), David’s Fulvetta (Alcippe davidi), and Huet’s Fulvetta (Alcippe hueti) were formerly united into a single species, known as the ‘Gray-cheeked Fulvetta’, but the four were recently separated, principally based on molecular data, although they are also weakly differentiated morphologically. Morrison’s Fulvetta is perhaps the best studied of the four species, thanks to numerous studies dedicated to its breeding and foraging behaviors.
