Sequential predictability of the scanning behaviour of greater rheas, Rhea americana
Some models that predict the scanning pattern to maximise the probability of predator detection by prey assume sequential randomness (i.e. lengths of inter-scan intervals are independent of each other and of the length of scan events). Sequential randomness would prevent stalking predators synchronising their attacks with long inter-scan intervals.

Using environmental enrichment to reduce the expression of abnormal behaviours in Greater rhea Rhea americana at Belo Horizonte Zoo. [PDF]
Animals kept by zoos may express abnormal behaviours that are indicators of poor welfare. Environmental enrichment is a technique of providing items to animals that stimulate the expression of normal behaviours.
