Crowing
The rooster is often portrayed as crowing at the break of dawn ("cock-a-doodle-doo") and will almost always start crowing before 4 months of age. He can often be seen sitting on fence posts or other objects, where he crows to proclaim his territory. However, this idea is more romantic than real, as a rooster can and will crow at any time of the day. Some roosters are especially vociferous, crowing almost constantly, while others only crow a few times a day. These differences are dependent both upon the rooster's breed and individual personality. He has several other calls as well, and can cluck, similar to the hen. Roosters will occasionally make a patterned series of clucks to attract hens to a source of food, the same way a mother hen does for her chicks.
