As it passes down the oviduct, a coat of thick albumen is accumu­lated and the disc becomes pushed to the upper side. The ovary and the oviduct of only oneside are functional during breeding season. Male Reproductive Organs: Sexes are separate and sexual dimorphism is absent in pigeon. Pigeon - Urinogenital system and Male, Female reproductive organs. Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly. The cloaca is a chamber and outlet which both male and female pigeons possess (and most birds), into which the intestinal, urinary, and genital tracts open. They open separately into the urodaeum of the cloaca through two different ureters. While passing down the oviduct, the ovum (fertilised or un-fertilised) becomes invested by the secretion of the various glands. Only the left ovary persists in the adult. The right ovary disappears during development. Birds possess feathers, beak and feet modified in relation to their aerial life. 1.127A). Between the tubules, groups of Leydig cells are present. In this paper, anatomical and physiological characteristics of the male and female bird will be presented in order These eggs are incubated by the parents for a fortnight at a temperature of 38° to 40°C. Then a tough shell membrane and a calcareous shell are added by the secretory acti­vities of the glands present in the oviduct.

The endocrine system consists of a number of organs and major glands located in different areas of the body which play an important role in the proper functioning of the animal. There is no copulatory organ. The last part of the vas deferens becomes slightly swollen to form seminal vesicle. Various glands are present in the inner lining of the oviduct. Veterinary practitioners frequently encounter disorders of the reproductive system in avian patients. Between the tubules, groups of Leydig cells are present. Each vas deferens runs posteriorly, parallel with the ureter and opens into the urodaeum at the tip of a small papilla. mudpuppy: male reproductive system - spermatophores from the male collect in the fall and store in the cloaca until spring - they are used to fertilize the eggs as they are laid. 26.47) are testes and vasa deferentia and there occurs no penis like mammals.
