Willis’ recent foray into the African plains in Kenya saw him returning with a rare image of a male Ostrich (Struthio camelus) caught with his penis exposed (left). This is one of a few bird species in which the male has a penis. And this is displayed prominently only during courtship.
Willis was on a morning game drive when the guide spotted what looked like Ostriches in the distant horizon. Moving closer, they realised that a pair of Ostriches was in the midst of a mating dance. Another female was loitering nearby. By the time the party arrived nearer to the birds, the female was in a submissive posture, indicating that she was ready for copulation. The male then mounted her, fluffing his wings and swaying his puffed out brightly coloured neck (below). Copulation lasted barely a minute. And according to Folch (1992), the male grunts and groans throughout copulation.
Gill (2007) has this to say: “The fully extended, bright red penis of an ostrich may be 20 centimeters long. The mating ritual of these large flightless birds is a dramatic event: intromission and ejaculation last a full minute.”

Wow! 20 cm hah? No wonder the ostrich was red in the face exposing it to Willie!
