A Catalina Macaw - a Blue-and-yellow Macaw x Scarlet Macaw hybrid.

A bird hybrid is basically 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.

Recognition

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

• Stork hybrid, including

interfamilial hybrids:

Ciconia nigra (Black Stork) X Ciconia ciconia (White Stork)

A spurious record given that inter-familial hybridization in birds is generally unheard of commonly name known as the 'Black and White Stork'

e.g.

• Parrot hybrids, including

interfamilial hybrids:

Neophema chrysostoma (Blue-winged Parrot) X Nymphicus hollandicus (Cockatiel)

A spurious record given that inter-familial hybridization in birds is generally unheard of.

intergeneric hybrids:

e.g.

Anodorhynchus hyacinthinus (Hyacinth Macaw) X Ara ararauna (Blue-and-yellow Macaw) commonly known as the 'Caloshua' Hybrid Macaw ;

Eolophus roseicapillus (Rose-breasted or Galah Cockatoo) X Nymphicus hollandicus (Cockatiel) commonly named the 'Galatiel' Hybrid Cockatoo

Eolophus roseicapillus (Rose-breasted or Galah Cockatoo) X Cacatua galerita (Sulphur-crested Cockatoo) Hybrid Cockatoo.

Platycercus eximius (Easterned or Golden-mantled Rosella) X Psephotus haematonotus (Red-Rumped Parakeet).

interspecific hybrids:

e.g.

Amazona ocrocephala (Yellow-crowned Amazon) X A. auropalliata (Yellow-naped Amazon) ;

Ara ararauna (Blue & Gold Macaw) X A. macao (Scarlet Macaw) commonly known as either the 'Catalina' (worldwide) &/or the 'Rainbow' (primarily in Australia) Hybrid Macaw ;

Aratinga jandaya (Jenday Conure) X A. solstitialis (Sun Conure) commonly known as the 'Sun-Day' Hybrid Conure.

intraspecific hybrids:

e.g.

Eclectus roratus solomonensis (Solomon Island's Eclectus) X E. r. vosmaeri (Vosmaeri's Eclectus) commonly known as the 'Solo-Vos' Eclectus,

Psittacula krameri krameri (African Ringnecked Parakeet) X P. k. manillensis (Indian Ringnecked Parakeet, a common feral species in parts of Europe)

• Captive songbird hybrids, such as Mules, (Canary x British Finch) and crosses of finch species.
• Corvus hybrids such as (Rook x Jackdaw), Rookdaw (Rook x Raven) Rooven and Carrion Crow x Hooded Crow (Common in the British isles where Carrion and Hooded crows interbreed freely, which is not really hybridisation as they are both simply colour-variants of the same species of bird).

• Birds of Paradise include several examples of both intraspecific and interspecific hybridisation.
