チビアオヒタキ Niltava macgrigoriae

Size distinguishes this species from other niltavas; coloration is quite similar to Large Niltava, which is double the size. Male Small Niltava is bright blue with the brightest patches on the shoulder and forehead. Female is brown with a white eyering and a rufous tail and wingtips. Forages in the lower and middle levels of hilly and montane forests, usually singly. Listen for its distinctive song, a cleanly descending “wee-dee-dee.”
