ミドリオナガムシクイ Urolais epichlorus

A distinctive apalis-like bird of scrub and forest edge in the mountains, where it is commonly encountered in small family groups. Dingy white below and uniformly green above. Named for its long, thin green tail feathers that can be longer than the rest of the body. While tail length varies by age and sex, it always appears relatively long. Song is a distinctive, rising series of psip-like notes, “ree-Ree-Ree-REE!”, sometimes given with a duetted “tik-tik-tik-tik.”
