Which bird is likely to be considered a 'hybrid'?

The answer is identified correctly as the choice discussing a raptor that is bred from two different species. A hybrid is defined as an organism that is the progeny of two different species or subspecies. In falconry and ornithology, hybrids can occur naturally but are often artificially created through breeding practices where two distinct species are mated. This can result in a bird with characteristics influenced by both parent species.

The other options do not meet the criteria for hybrids. A bird with its origin from a single species cannot be classified as a hybrid since it lacks genetic contribution from another species. An adult bird that has fully fledged simply describes its developmental stage and does not indicate any hybrid characteristics. Lastly, a wild bird that does not conform to typical species characteristics may be unusual or mutated but does not imply that it is a hybrid in the context of breeding traits. Thus, the definition aligns perfectly with the characteristics outlined in the choice focusing on raptors bred from different species.
