Monogamous birds

Around 90% of the world's bird species are monogamous. This means they have one mate at a time. Most will not pair for life though and their partner may change each breeding season. Some birds have several broods each season and may produce each one with a different partner.

Are birds genetically monogamous?

Avian monogamy is usually defined socially or genetically, whereas quantifications of sexual behavior remain scarce. Jackdaws (Corvus monedula) are considered a rare example of strict monogamy in songbirds, with lifelong pair bonds and little genetic evidence for extrapair (EP) offspring.

Why do monogamous birds cheat?

Birds may cheat on their mates to avoid the harmful effects of inbreeding, biologists say. While human infidelity may be motivated by any number of reasons, scientists say cheating by socially monogamous shore birds seems to provide greater genetic diversity when they are already paired to genetically similar partners.

Are all birds polygamous?

Birds That Mate for Life Most birds are far from monogamous. Most birds do not mate for life, and most of those that do aren't quite as faithful as we'd like to think. Over 92 percent of all bird species form a pair bond and stay together for at least part of the nesting cycle.
