	Pigeon intelligence - Wikipedia, the free encyclopedia
		Additionally pigeons are one of six species to pass the mirror test — which tests whether an animal recognizes its reflection as an image of itself — along with common chimpanzees, bonobos, orangutans, dolphins and humans.
		Pigeons have featured in numerous experiments in comparative psychology, including experiments concerned with animal cognition, and as a result we have considerable knowledge of pigeon intelligence.
		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

	Rock Pigeon - Wikipedia, the free encyclopedia
		Current (2004) research in pigeons is widespread, encompassing shape and texture perception, exemplar and prototype memory, category-based and associative concepts, and many more unlisted here (see Pigeon intelligence and discrimination abilities of pigeons).
		Pigeons' extraordinary navigation abilities are in part due to the fact that they are able to sense the Earth's magnetic field with tiny magnetic tissues in their head.
		Pigeons are widely considered vermin, owing to concerns that they spread disease, damage property, cause pollution with their excrement, and drive out other bird species; they are sometimes dubbed sky rats or gutter birds.

	Discrimination abilities of pigeons - Wikipedia, the free encyclopedia
		They were then able to generalize, and correctly discriminate between paintings of the two painters not previously shown, and even between cubist and impressionist paintings (cubism and impressionism being the two stylistic schools Picasso and Monet belong to).
		In a later paper, Watanabe showed that if pigeons and human college students undergo the same training, their performance in distinguishing between Van Gogh and Chagall paintings is comparable.
		Similar experiments had shown earlier that pigeons can be trained to distinguish between photos showing human beings and those that do not, and between photos showing trees and those that do not, among many other examples.

	dove
		Unlike most other birds, (but see flamingo), the doves and pigeons produce "crop milk", which is secreted by a sloughing of fluid-filled cells from the lining of the crop.
		Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere.
		To be referred to as a "pigeon" or a "dupe" suggests unwariness in the person deluded - especially used in the slang language of gambling - Etymology: French, from Middle French duppe

	Birds' Judgments of Number and Quantity
		In the experiment on proportion discrimination with pigeons, the stimulus conditions described so far utilized stimuli in which the proportions of ‘correct’ color in the paired positive and negative stimuli were complementary.
		Pigeons were trained, for instance, to approach a strip of cardboard on which there were two sets of grain that differed in number.
		Since a non-linear discrimination function was obtained when behavioral scores were measured on a scale of percentage of correct choices, these behavioral measures were linearized by converting the scores to a logit scale (defined as ln(% correct/(100 - % correct)); Macmillan and Creelman, 1991).

	Learning Theories Lecture Thirteen
		Most pigeons usually are better than 90% most of the days of training.
		Pigeons do have control of the contents of their working memory.
		The idea was that if we could signal the pigeon that it does not need to remember the sample stimulus, because no comparison stimuli would occur, and the pigeon then "forgot" it, or dumped it from consciousness, we would have evidence that pigeons can also control what and when they will remember.

	Models of Learning and Performance
		The first pigeons were trained in a typical MTS procedure of requiring one peck, fixed ratio of one (FR1), to the sample to produce the comparison stimuli.
		Pigeons were trained on 6 of these 12 displays.
		Pigeons are predisposed to memorizing as opposed to relational learning, relative to primates such as rhesus monkeys (Wright, Santiago, Sands, and Urcuioli, 1984; Wright, Cook, and Kendrick, 1989).

	RESEARCH - INTERESTS
		The published data seem to indicate that birds have developed symmetry discrimination abilities, for example pigeons can learn to distinguish symmetry from asymmetry and then generalize this discrimination to novel stimuli.
		It is not clear whether such abilities reflect the existence of an innate (rather than acquired) category for symmetry.
		In animal visual perception, detection of symmetry is a crucial ability, since symmetry is inherent to most living creatures.
