Hadeda ibises (Bostrychia hagedash) are one of the most familiar species of birds across sub-Saharan Africa. They are large, long-legged birds with long, thin beaks for probing invertebrates out of soil, and though they appear dull brown at a glance, they actually have beautiful iridescent feathers on their wings. But they are best known for their loud, laughing calls, which often ring out early in the morning, winning them the title of "African alarm clocks."
