This is Marabou stork, the undertaker bird. Yorùbá call them àkàlàmàgbò. Even though some people often claim that the ground hornbill is àkàlàmàgbò (I also used to do that in the past), sitting with elders and looking into old documents confirmed that Marabou stork is the real àkàlàmàgbò.
What is a marabau stork, never heard of that.
