Strange features are no better than no features: predator recognition by untrained birds.

ABSTRACT: Predator recognition is essential for prey survival, allowing for appropriate antipredator strategies. Some bird species, such as the red-backed shrike (Lanius collurio), distinguish not only between predators and non-threatening species but also between different predator species. Earlier studies have identified general predator "key features", especially beak shape and talons, as critical for predator recognition. The question, though, still remains of whether exchanging predator key features with those of nonpredatory species or, alternatively, completely removing them, have different or equal impact on recognition. Here we tested to ascertain whether the presence of the "incorrect key features" of a harmless pigeon (Columba livia) placed on a common kestrel (Falco tinnunculus) body imp
