Global InformationEnglish Fallow budgerigar mutation information
The English Fallow budgerigar mutation is one of approximately 30 mutations affecting the colour of budgerigars. At least three types of Fallow, the German, English and Scottish, all named after their country of origin, have been established, although none of these types is common. They are superficially similar, but adult birds may be distinguished by examining the eye. All have red eyes, but the German Fallow shows the usual white iris ring, the eye of the English Fallow is a solid red with a barely discernible iris and the iris of the Scottish Fallow is pink.
In an attempt to regularise the names of mutations across all psittacines, it has been proposed by Inte Onsman[1] that the name Pale Fallow be adopted for this mutation. The name Dun Fallow has also been proposed, and Terry Martin suggests[2] Beige Fallow or Grey-Brown Fallow. But in Budgerigar circles the variety is commonly known as the English Fallow, and is the name retained here.
