It is plump and long-legged. An eBird/Merlin identification account describes a red belly and collar, dark blue wings, a greenish back, a red crown, and a pale blue chest. Island populations can differ in color.
It is mainly ground-dwelling in primary forest and along forest edges. The IUCN assessment describes it as resident and records it in primary rainforest and secondary growth up to about 1,200 m.
An extinction-risk assessment has not been added yet.
