Beyond the base coloring of a rosy-faced lovebird, there are mutations that exist independently of any other mutation. These mutations are of three distinct types: co-dominant (exemplified by the Orangefaced, Dark and Violet mutations), recessive (exemplified by the Edged Dilute mutation), and sex-linked (exemplified by Lutino, Pallid [also known as Australian Cinnamon], American Cinnamon, and ...
The rosy-faced lovebird is a fairly small bird, 17–18 cm (6.7–7.1 in) long, with an average wing length of 106 mm (4.2 in) and tail length of 44–52 mm (1.7–2.0 in). [4] Wild birds are mostly green with a blue rump. The face and throat are pink, darkest on the forehead and above the eye.
The lutino peach-faced love bird (Agapornis roseicollis) is one of the most popular mutations of rosy-faced lovebird. It is closely followed by the Dutch blue lovebird in popularity. [ 1 ]
Some think the red-pied has some genetic relations with the Lutino rosy-faced lovebird mutation, as many cases of red spots appear in Lutino lovebirds. Although many breeders of parrots have claimed that this is a genetic mutation, no one has been able to successfully reproduce it through a series of generations. [1]
This mutation was first bred by R. Horsham in South Africa in 1957. There is a yellow lutino mutation, which first appeared in France. These birds are typically pale yellow with an orange face and a red beak. Further mutations are pied, black or dark eyed white, cinnamon, white, and albino mutations that have also been bred.
Lovebird is the common name for the genus Agapornis, a small group of parrots in the Old World parrot family Psittaculidae.Of the nine species in the genus, all are native to the African continent, with the grey-headed lovebird being native to the African island of Madagascar.
The blue mutation was originally found in wild birds in the 1920s and is the oldest colour mutation known in the lovebird genus. [4] [6] The other mutations are a result of selective breeding in aviculture, such as two cobalts which will make a mauve (black). [4]
Birds' point mutation rate (1.9 × 10 −3 mutations per site per Ma) is smaller than that of mammals (2.7 × 10 −3 mutations per site per Ma). This rate is also smaller among aequornithes (water birds) than that of telluraves (land birds). In this last group, birds of prey have the smallest mutation rate, and songbirds have the highest.
