Orange Senegal hen; note the head & neck area; it lacks the pinkish/purplish coloration of the Tangerine & Normal Senegal.
Orange Senegal - open wing. Note the much whiter colored feathers then in a Tangerine.
The Orange Senegal was produced in 2000 by John Pire. This color is the "dilute" of Tangerine. It is recessive to the Tangerine & Normal colored birds. When Orange is bred to Tangerine or Normal birds all young will either be Tangerine or Normal. All of the males produced will carry the "dilute" gene hidden. This gene works exactly as it does in the Ringneck Dove (Streptopelia risoria). Breeding the Orange to a Tangerine will produce a percentage of "pearled" young. The young "pearled" males will carry the "dilute" gene hidden.
