The fischer´s lovebird has a green back,chest,and wings.Their necks are a golden yellow and as it progresses upward it becomes darker orange.The top of the head is olive green,and the beak is bright red.The upper surface of the tail has some purple or blue feathers.It has a white circle of bare skin (eyering) around it eyes.Young birds are very similar to the adults except for the fact that they are duller and the base of their mandible has brown markings.They are one of the smaller lovebirds,about 14 cm.(5.5 in) in lenght and 43-58 weight.
While most Fischer´s Lovebirds are green, several color variations have been bred.The blue variation is predominant; lacking yellow, it has a bright blue back, tail, and chest, a white neck, a pale grey head and a pale pink beak.
This mutation was first bred by R.Horsham in South Africa in 1957, and two years later (1959) was bred by Dr.F.Warford in San Francisco,California.
I think that is one of the most beautiful birds in the world.They had beautiful colors in their wings and in the beak.They are exotics animals.I like the colors of the animal.
