1 What do we know about predator recognition by untrained birds?.- 1.1 The study of predator recognition (How to make birds respond in etho-ecological experiments - to show that they recognized the predator - nest defense, feeder experiments, laboratory experiments.).- 1.2 Evidence for predator recognition ability (What predator categories birds recognize - predator vs. non-predator, aerial vs. terrestrial predators, individual predator species.).- 1.3 Tools used for predator recognition (What cues bird use for predator recognition - sign stimuli, coloration, size.).- 2 What can the recognition experiments with trained pigeons tell?.- 2.1 Category discrimination and concepts formation (How do birds form categories of predators - memorizing vs. generalization vs. conceptualization.).- 2.2 Object recognition (What cues birds use for predator recognition - particulate feature theory vs. recognition by components, local vs. global features.).- 2.3 Other cognitive processes (Are we able toreveal other cognitive processes in predator recognition by birds - amodal completion, priming.).
