Compare models which may explain female birds' choice of mates. Observe how females "test" potential mates and how males provide a basis for choice, through courtship displays or offering prime territory. Study the intricacies of avian monogamy and polygamy; take account of pair bonding in birds, extra-pair mating, sexual role reversal, and the avian equivalents of "adultery" and "divorce."

Begin by contemplating the integral connections between birds and dinosaurs. Examine mounting evidence that birds not only evolved directly from dinosaurs, but also that they are themselves dinosaurs. Consider how bipedal reptiles gained the ability to fly, becoming birds, and how the cursorial (from the ground) and arboreal (gliding) theories of the origin of flight may intersect.

Track the behavior of birds when they form flocks or colonies. Grasp the diverse benefits of group foraging, and how birds form mixed-species foraging flocks. Investigate group roosting and breeding behavior, and study fossil evidence that suggests some dinosaurs nested just like modern wading birds. Assess why birds form colonies and investigate the advantages and disadvantages of the colonies.

Learn how birds mate; then examine the structure of bird eggs, how they are laid, and how laid eggs develop. Observe how nests are constructed, the diverse materials used to build them, the types and functions of nests, and the range of ingenious avian nesting behavior. Finally, explore how birds incubate their clutch, and study brood parasites, who lay eggs in the nests of other birds.

Witness the complex nature of competition among birds. Study "display" behavior, which sends a message regarding territory, courtship, or perceived threats. Observe the ways in which birds defend territory, for breeding and feeding, nesting and roosting. Note how territorial defense is highly ritualized and uses a series of recognized signals, and how birds' territoriality enhances survival.
