Indochinese Blue-flycatcher (Cyornis sumatrensis)


French: Gobemouche d’Indochine German: Indochina-Blauschnäpper Spanish: Papamoscas indochino

Siphia sumatrensis


, 1879,



Hitherto treated as conspecific with C. tickelliae, but differs in its (in female) lack of blue brow-flash (2); browner, less blue upperparts (1); darker rufous breast (1); and (in male) song a clear descending trend (most phrases with first notes higher and last notes lower) and phrases with fewer than 10 notes vs song of fast tinkling notes (typically 10 to a phrase; score 1) which randomly change in pitch without a descending trend (2)#R. Some evidence of hybridization also between present species and C. banyumas in Malay Peninsula. Three subspecies recognized.
