Whilst we are waiting for the next season of Snapshot Serengeti images I have been reviewing some of the amazing images that season 11 turned up. I always have to remind myself that these cameras do not have some avid photographer sat behind them snapping away at the opportune moment but are activated merely by sensing a change in heat within their detection zone. It is truly amazing how often we get stunning images.
Here a beautiful male ostrich struts across the field of view showing off his amazingly pink legs. The bare parts of male ostrich are usually a pale grey to pink colour but during the breeding season hormones influence the pigmentation and a flush of red blazes through his neck and legs. Given the extent of these legs and neck contrasted with the bold black and white feathers it makes for an arresting sight. Compared with the drab browny grey of the female the male is a real show off.
What’s strange about this scenario is that in most bird species where the male changes feather of bare parts colour it is the female alone that rears the chicks. The colourful male would perhaps attract too much predator attention around the vulnerable nest or chicks. In ostrich though, the male takes his share of sitting on eggs and looking after chicks. In fact he and his primary female will take turns incubating a clutch of eggs that typically include both hers and other females eggs so he will generally have more invested in the chicks as a direct parent than the female who may only be ‘aunt’ to some of the chicks.
I guess the shear size, power and speed of the ostrich, who is perfectly adapted to the open plains of the Serengeti, means he can afford the fancy show of pink legs if it means winning the ladies.
