Black-naped Monarch

The black-naped monarch is a monarch flycatcher found in southern and south-eastern Asia. The adult male is about 16cm long and mainly pale azure-blue apart from a whitish lower belly, with a distinctive black patch on the back of the head and a narrow black half collar. The female is duller, with olive-brown wings and without the black head markings (Wikipedia, general species account).

Two to three eggs are laid in a cup nest placed in the fork of a tree and decorated with spider-egg cases. The call is similar to that of the Asian paradise flycatcher, and in tropical forest habitats pairs may join mixed-species foraging flocks. Geographically separated breeding populations differ in the extent and shade of colour (Wikipedia, general species account).
