Bird hybrid

A bird hybrid is a bird that has two different species as parents. The resulting bird can present with any combination of characters from the parent species, from totally identical to completely different. Usually, the bird hybrid shows intermediate characteristics between the two species. A “successful” hybrid is one demonstrated to produce fertile offspring after mating.

The description of bird hybrids results from observations in nature combined with those obtained in captivity such as in zoos per example.
