Over the last 50 years four theories of predation have emerged which explain a predator's prey selection. Tinbergen (1960) proposed that search image is the dominant factor when novel cryptic prey is the goal. Others feel that conspiciousness, search rate, and oddity are important. The newest controversy to emerge is the oddity on search rate, 1 cougar will be studied with and without an oddity stimulus (odd deer). It is expected that the cougar will spend more time watching the deer when it is "odd" than when it is not, and that predatory attending behaviours will increase with the presence of the odd stimulus.
