|Pigeons are a common site therefore we tend to overlook them but they are beautiful. This is a close up of ones feathers :)|
Some interesting facts:
-Pigeons have the capacity to share attention between different dimensions of a stimulus, but (like humans and other animals) their performance with multiple dimensions is worse than with a single stimulus dimension.
-Pigeons can be taught relatively complex actions and response sequences, and can learn to make responses in different sequences.
-Pigeons readily learn to respond in the presence of one simple stimulus and withhold responding in the presence of a different stimulus, or to make different responses in the presence of different stimuli.
-Pigeons can discriminate between other individual pigeons, and can use the behaviour of another individual as a cue to tell them what response to make.
-Pigeons readily learn to make discriminative responses to different categories of stimuli, defined either by arbitrary rules (e.g. green triangles) or by human concepts (e.g. pictures of human beings).
They do less well with categories defined by abstract logical relationships, e.g. "symmetrical" or "same", though some experimenters have successfully trained pigeons to discriminate such categories.
-Pigeons seem to require more information than humans for constructing a three-dimensional image from a plane representation.
-Pigeons seem to have difficulty in dealing with problems involving classes of classes. Thus they do not do very well with the isolation of a relationship among variables, as against a representation of a set of exemplars.
-Pigeons can remember large numbers of individual images for a long time, e.g. hundreds of images for periods of several years.
