Therefore the situation is not one in which mated pairs rear only their Mature Eastwood, Ontario milf offspring, as traditional use of the term monogamy has implied.
Sexual exclusivity is not part of the above criteria. Increasingly, ornithologists and behavioral ecologists have come Free hot teens phone sex talk view Monogamy meaning as part of a "mixed" reproductive strategy in which matings may occur outside the primary pair bond, but both members of the pair still contribute substantially only to the care and feeding of the young from their own nest.
The traditional view of why more or less permanent monogamous bonds are formed is changing, as interest has become focused on the parentage of offspring reared by "monogamous" pairs. Credit: Lim et al.
