In an analysis of hunting by African lions, biologists filmed prey captures from the safety of their vehicles.\u00a0 Prey captures were then divided into a sequence of events.\u00a0\u00a0 One of the events is the stalk, defined as the reduction of predator-prey distance for prey that has been specifically targeted.\u00a0 The investigators identified two types of stalk: (a) “crouching,” — the lion is concealed and either the lion advances toward the prey or the prey advances (unaware) toward the lion, and (b) “running,” — the lion is less concealed and advances toward the prey in a rapid manner.<\/span><\/p>\n

The same monitoring of radio-collared lions over the years suggests that the overall proportion of stalks that are the crouching type is about 0.87. Do the data above provide evidence that for this population of lions the proportion of crouching stalks of wildebeests and zebras is greater than what was originally thought?
