Predator Recognition in Birds

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…).
