Bird 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.

Additional recommended knowledge

Recognition

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

There are no field guides that illustrates bird hybrids. The photographs, illustrations and descriptions can be found in the literature or on websites. There is, depending on the literature, anywhere between 9,900 and 10,000 bird species throughout the world.

  • Red Kite x Black Kite (unintended, in a falconry center)
  • Parrot hybrids, including

inter-familial hybrids :

i.e.

Neophema chrysostoma (blue-winged Parakeet) X Nymphicus hollandicus (Cockatiel Parakeet)

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

inter-generic hybrids :

i.e.

Anodorhynchus hyacinthinus (Hyacinth Macaw) X Ara ararauna (Blue & Gold 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 ;

Platycercus eximius (Easterned or Golden-mantled Rosella) X Psephotus haematonotus (red-rumped Parakeet)...

inter-specific hybrids :

i.e.

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 (Janday Conure) X A. solstitialis (sun Conure) commonly known as the 'Sun-Day' Hybrid Conure...

intra-specific hybrids :

i.e.

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 aka ARN Parakeet) X P. k. manillensis (Indian-ringnecked aka IRN Parakeet, a common feral species in parts of Europe)

  • Captive songbird hybrids, such as Mules, (Canary x British Finch) and crosses of finch species.
