Deuteronomy21:10-17
10 "When you go out to battle against your enemies, and the LORD your God delivers them into your hands and you take them away captive, 11 and see among the captives a beautiful woman, and have a desire for her and would take her as a wife for yourself, 12 then you shall bring her home to your house, and she shall shave her head and trim her nails. 13 "She shall also remove the clothes of her captivity and shall remain in your house, and mourn her father and mother a full month; and after that you may go in to her and be her husband and she shall be your wife. 14 "It shall be, if you are not pleased with her, then you shall let her go wherever she wishes; but you shall certainly not sell her for money, you shall not mistreat her, because you have humbled her.
15 "If a man has two wives, the one loved and the other unloved, and both the loved and the unloved have borne him sons, if the firstborn son belongs to the unloved, 16 then it shall be in the day he wills what he has to his sons, he cannot make the son of the loved the firstborn before the son of the unloved, who is the firstborn. 17 "But he shall acknowledge the firstborn, the son of the unloved, by giving him a double portion of all that he has, for he is the beginning of his strength; to him belongs the right of the firstborn. |

| | | 426319 | Mar 12, 2007 9:04am | | i think love birds mate for life, and i'm sure some humans do too, there's a distinction between love and sex that gets blurred: for instance my partner used to stumble, and would get insanely jealous when i flirted, they didnt consider it "cheating" however because that's how i am in real life |

Sponsor | | Thomas-Jefferson | Mar 12, 2007 3:00pm | 'Mating systems and parental care
The three mating systems that predominate among birds are polyandry, polygyny, and monogamy. Monogamy is seen in approximately 91% of all bird species. Polygyny constitutes 2% of all birds and polyandry is seen in less than 1%. Monogamous species of males and females pair for the breeding season. In some cases, the individuals may pair for life.
One reason for the high rate of monogamy among birds is the fact that male birds are just as adept at parental care as females. In most groups of animals, male parental care is rare, but in birds it is quite common; in fact, it is more extensive in birds than in any other vertebrate class. In birds, male care can be seen as important or essential to female fitness. "In one form of monogamy such as with obligate monogamy a female cannot rear a litter without the aid of a male" (Gowaty, 1983).
The parental behavior most closely associated with monogamy is male incubation. Interestingly, male incubation is the most confining male parental behavior. It takes time and also may require physiological changes that interfere with continued mating. This extreme loss of mating opportunities leads to a reduction in reproductive success among incubating males. "This information then suggests that sexual selection may be less intense in taxa where males incubate, hypothetically because males allocate more effort to parental care and less to mating" (Ketterson and Nolan, 1994). In other words, in bird species in which male incubation is common, females tend to select mates on the basis of parental behaviors rather than physical appearance. '
