Feather pecking occurs when one bird repeatedly pecks at the feathers of another. He frequently doles out handshakes, half-hugs and, to women, pecks on the cheek. Two pecks make a kenning (obsolete), and four pecks make a bushel. Instead, he kicks and pecks them with his snout. The male pecks its folded wings in "displacement-preening" to solicit copulation from the female. Before long, the pigeon pecks at the disk (or stimulus) regularly. The bird also pecks out the horses' eyes. Woody then pecks his name into a tree. The birds were rewarded for pecks at a picture showing a moth. Meanwhile, the village headman still pecks at Sarada. Their rebellion against the Han dynasty is known as the Five Pecks of Rice Rebellion. In 142 CE, Zhang Daoling founded the Five Pecks of Rice religious society in Sichuan. A firlot was equal to 4 pecks. If it chooses (pecks) the matching comparison, then it is rewarded. The schedules of reinforcement arranged for pecks on the two keys can be different.
