The African Sacred Ibis has a size of 65 to 89 centimeters. This bird has long legs and a slender, curved beak. The bald head and neck have black skin. The plumage colors mainly white with black tipped wings, with a green sheen. This bird species has blue-black ornamental plumes, which fall as a tuft over the short tail.
Because temperatures in Africa can be quite high throughout the day, the African Sacred Ibis has developed a system to dissipate the heat. Namely, this bird species uses ‘gular-fluttering‘. With “gular-fluttering,” the bird opens its beak and “flutters” with its neck muscles. As a result, heat loss occurs.
