An elongated, metallic-green-black bird with red feet and a long, decurved, red-orange bill. Juveniles have dark bills but are often in the company of adults. It flies heavily, with the long floppy, white-tipped tail dangling behind. Pairs and groups of up to 14 birds are highly social, occupying savanna, woodland, riverine forest, and gardens, where they nest and roost in natural cavities. Clambers in trees, probing bark and crevices for insects and small vertebrates. They communicate using a strong cackling chatter that sounds maniacal. The almost identical Grant’s and Violet woodhoopoes (with which it sometimes hybridizes) differ from Green Woodhoopoe only by having a coppery-purple (not glossy greenish) metallic sheen.
