Species had three kinds of diets during the non-breeding season:(1) mainly invertebrates,(2) mainly fruits, and (3) mainly nectar. This study demonstrated that the diets of 14 passerines during the non-breeding season were significantly correlative with tongue morphology (r=0.424, P .05) and were most correlative with brush length and width of the 3/4 position (r=0.62, P.05). For example, Yuhina brunneiceps's primary diet is nectar and it has the brush-tipped tongue with the longest brush length. Niltava vivida mainly forages for fruits and has a tongue with longer width of the 3/4 position.
