Imitation and Affordance Learning by Pigeons (Columba livia).

Journal of Comparative Psychology, 2003
The bidirectional control procedure was used to determine whether pigeons (Columba livia) would imitate a demonstrator that pushed a sliding screen for food. One group of observers saw a trained demonstrator push a sliding screen door with its beak (imitation group), whereas 2 other groups watched the screen move independently (possibly learning how ...

Nodding: an Appeasement Behaviour of Pigeons (Columba Livia)

Behaviour, 1989
A variety of displays performed by social animals in agonistic encounters are termed "appeasement behaviours", although experimental proof of the appeasing effect is rare. In pigeons, nodding occurs in both sexes during courtship and pair formation, often in response to an aggressive act of the mate.

Flight stimulates adrenocortical activity in pigeons (Columba livia)

General and Comparative Endocrinology, 1986
The influence of long-distance flight on corticosterone secretion has been examined in trained racing pigeons. Flights of 315-561 min from release sites 115-557 km from the home loft greatly increased the circulating corticosterone concentration in comparison with the levels in nonexercised controls sampled before release or bled in the loft at the ...

A myological illustration of Columba livia

Journal of the Yamashina Institute for Ornithology, 1971
The myological illustrations here presented are based on more than ten examples of Columba livia (Carrier Pigeons killed by cats), studied during 1945-46. The illustrations have been so devised as the origin and insertion of each muscle could be shown not hidden by other muscles, by restricting the number of muscles in one illustration.
