World first Fallow Yellow-Crowned Amazon



 First for South Africa and most probably the First in the World.



Fallow Yellow-crowned Amazon

During the breeding season of 2011 the unexpected has happened, the hatching of Yellow-crowned Amazon’s with ruby red eyes, what makes the event that much more memorable is that four out of five chicks had red eyes.

History of the breeding pair:

The breeder has got a breeding pair that bred for many years, and during 2003 four babies was kept for breeding. These four birds turned out to be two pairs, two related pairs. The one pair started to breed in 2009. That year as well as 2010 gave no surprises, everything happened in 2011. All young were exported, including the normal birds of the original breeding pair in 2011. Three of the red-eyed birds died early and one red-eyed and one normal baby where rose and kept.  With this high percentage of mutation birds, it is most likely that the mutation was inherited by both parents, from one of the birds in the original breeding pair. It may be that any of the brother and sisters could carry the mutation, with this in mind; the establishing of the mutation could be fast tract.  


 Description of the Fallow bird.

Body:  Breast, abdomen and throat; Yellowish green

Head:  Fore-head; more yellowish with the yellow-cap a lighter shade of yellow.

Back:  Wings green with a brown sheen to it.

Tail:  More yellow above, than the normal birds.

Feet:   Flesh coloured;   not grey as in normal birds.

Beak:  Horn –coloured with light grey to the ends

Eyes:  Ruby red with no white iris.


 The Fallow mutation.

Four forms of Fallow exist, all with similar features. All have red eyes and a down toning of colour. The black (eumelanin) and brown (phaeomelanin) are reduced.

Pale Fallow – 80% of brown and black pigment reduced, no white iris

Bronze Fallow      50% of black pigment reduced, with white iris, cock and hens may differ in shade

Dun Fallow – 50% of brown pigment reduced, no white iris

Smoky Fallow – 20% of brown and black pigment reduced, with white iris

All indications are that this bird could be a fallow and most probably a Bronze Fallow, time will tell. The ability to have this mutation established in captivity is slim if one person is responsible for the task. Establishing the Fallow mutation means having patience, dedication and time to succeed. The new mutation should be bred with as many normal birds as possible, being that it is, Amazons that cannot be swopped around at will, to get half-brother and –sisters.

The possibility do exist that this bird could be an altogether other mutation, the name recessive Lime (Pastel) comes to mind, if so the establishing of this mutation should be much easier.
