Family Monarch-flycatchers (Monarchidae)

Least Concern

Pale-blue Monarch (Hypothymis puella)


French: Tchitrec des Célèbes German: Sulawesimonarch Spanish: Monarca azulado

Myiagra puella


, 1863,

Manado, north Sulawesi


Until recently normally considered conspecific with H. azurea, but differs in its lack of black nuchal patch (3); reduction to “shadow” (or nothing) of black breastbar (2); softer, less intense blue on crown, throat and breast, also upperparts and tail (2); “more variable and whistling” song (no score; see below); moreover, molecular evidence suggests this split#R. Arrangement is, however, provisional and caution needed, as two small-island forms, H. a. aeria (Maratua, off E Borneo) and H. a. abbotti (Lasia and Babi, near Simeulue, off W Sumatra), do not conform with other taxa under H. azurea (which see, above); moreover, currently available recordings suggest that race blasii conforms more with H. azurea in voice and does not share distinctiveness of nominate, hence no score (yet) for voice#R. Suggestion in HBW that H. a. catarmanensis belongs with H. puella mistaken. Two subspecies recognized.
