Genetic – sole biological parents of the young

Social – a male cooperates with a female in parenting even if not the parent of the young in the brood

Monogamy

Page 22: Bird Behavior: An Overview Bird Behavior: An Overview.

Polygyny, Polyandry, Polygynandry

Polygyny: Male multiple partners. Little, if any parenting.

Polyandry: Female multiple partners. Lays eggs in separate nests. Males help incubate, hatch, and rear young.

Polygynandry : Both females and males of a few species may have multiple partners who may use the same nest for their eggs. Jealous behavior may occur resulting in loss of eggs.

Breeding OptionsTerritorial Male wins female Copulate Builds & defends their nest

Colonial Several pairs share and

protect breeding site They help find food

Cooperative/CommunalMore than 2 birds of same species help feed, protect, & rear young. May be offspring from prior season. May exhibit shared maternity, shared paternity, or both. Florida Scrub Jay is an example.
