Lipid Metabolism,atter two groups of phospholipids were originally classified as “cephalins.” Other phospholipids yield glycerol, fatty acids, phosphoric acid, and the cyclic polyalcohol inositol (phosphatidyl inositol).

Sense Organs,in mammals. With a few interesting exceptions, the bird is a vision-oriented animal and it has been used extensively in research on vision. More detailed reviews on the subject of avian vision can be found in King-Smith (1971), Pearson (1972), and Sillman (1973).

Alimentary Canal: Anatomy, Prehension, Deglutition, Feeding, Drinking, Passage of Ingesta, and Motius, gizzard, intestines, ceca, rectum, and cloaca (see Figure 9–1). The lengths of various parts of the tract vary with size of the bird, type of food eaten, and other factors. Birds eating coarse, fibrous food tend to have especially large digestive tracts, and grain-eating birds have larger tracts than carnivores do.

Hypophysis,reas, (6) the testes and ovary (gonads), (7) the ultimo-bronchial glands, and (8) the intestine. The thymus and pineal bodies, which are sometimes classified as endocrine organs, are present in the bird but their functions are not clear.

Reproduction in the Female and Egg Production,stages, they usually do not persist in adult life. A persistent right ovary and oviduct have been reported in some avian species (raptors) and in rare instances in ducks and chickens where both ovaries and oviducts were functional (see Sturkie, 1965; Lofts and Murton, 1973).
