Abstract

The Taiwan Yuhina (Yuhina brunneiceps) and White-eared Sibia (Heterophasia auricularis) are nectar-feeding babblers endemic to Taiwan. We describe the morphological features of the brush-tipped tongues of these species. The tongue divides into two parts and then into four parts towards the distal end for both species. The tongues of the Taiwan Yuhina and White-eared Sibia are specialized organs adapted for collection of nectar.
