Black-naped Monarch Flycatcher (Black-naped Blue Flycatcher)
Hypothymis azurea (Passeriformes - Monarchidae) is a species of Southeast Asia with many subspecies. It is sexually dimorphic, males being blue and with collar on lower throat and nuchal patch black; females are duller and lacks the black markings.
The nest of the Black-naped Monarch Flycatcher is a deep compact cup of fibre and bark-like material, as well as fungal hyphal clumps, cob webs, spider eggs sacks and cocoon silk which is used as an anchorage material for attaching green moss.
Nest building is done by both male and female parents, although it has been reported to be predominantly done by the female. Brooding and feeding of the chicks is done by both parents.
