Then we see an intermediate colour appearing. Juan Manuel Escudero says: The hen will lay four to five eggs which are incubated for about 23 days. LaBrenda Herny – Alexis, This is up to you. Like blue, turquoise and aqua are autosomal recessive mutations. These are aqua and turquoise. In the past people thought that this was a different colour and so a different name was given for these phenotypes.

With these young you are certain that all green young are split blue, the other ones are normal blue. A lovebird is a very social bird with it’s companion, and it is generally thought to be essential for their good health and happiness that they be kept in pairs rather than singly.

Dutch Blue Lovebird, Dutch Blue Peach-faced Lovebird, Agapornis roseicollis var.

She climbs to my shoulder she’s even on it as I type this and it’s her favorite hangout. We still have the blue light, which was formed in the spongy zone, but the yellow filter is missing.

Young Tarantas — Medium Green on the right. Rooseicollis the years blue mutations appeared in many species.

On request: Blue, aqua and turquoise mutations in Lovebirds – Dirk Van den Abeele

They are intelligent little birds and make a wonderful companion and friend. This often causes typical jargon. Contrary to aqua, turquoise gives a more variable reduction of the psittacin in the feathers. Agapornis-personatus Facebook page Agapornis-personatus. A first step is to combine these mutations with pure wildtype birds, to exclude the presents of other alleles and ensuring that we start with homozygote birds.

This means that combining these alleles with green gives normal green split birds. Please note on the article see Article tab that the author, Didier Mervilde, serue permission from Mr. Roseicollis — Whitefaced Medium Aqua.


The Dutch Blue Lovebird is excellent for the beginning breeder. A clear example of this we roweicollis find, among others, in ring-necked parakeets.

One finger, feel around pelvic bone. Out of curiosity Dirk, what happen to the large number Comparative Biochemistry and Physiology, Part B, 3 I will put them down for you.

Good thread this, even though it’s named “rare mutations”, which it was until Marc posted tons of photos of common mutations: This mutation inherits autosomal recessive compared to the wildtype. For most breeders these PPR mutations short for Partital Psittacin Reduction are difficult to understand and these forms were often seen as to be developed blue colours. It becomes even more complicated within a species where we can find blue, turquoise and aqua.

Dutch Blue Lovebird

Can this be an accurate indication of a pied bird? Other external causes could be: The difference in mask colour in both of these species is simply sfrie by the fact that we have different mask colours in the wildtype birds, and so a different psittacin combination.

This was a logical explanation, but scientifically not correct as we can only speak of a dominant inheritance when a mutation is dominant over the wild form. We now know that green feathers in lovebirds get their blue colour due to the disappearance of the normally present yellow psittacin. Between them l had the joy of watching them courting, and rearing a large family of eight over.

I will now give some examples based on turquoise and blue. Green Euwing — Courtesy Billy Roseiocllis. Dyck, ; Jan Dyck, With this mutation we see an equal reduction of the present psittacin. Amy – l had a pair of Peach Faced lovebirds, as l was cleaning the roeicollis the female flew off. Have raised Love Birds for years and this can be tricky. Bblu fischeri — Courtesy Fabio Tarazona. We will describe this colour segie simply by writing the present mutated alleles together in one name.


Both aqua as turquoise inherit autosomal recessive against the wildtype. When you provide them with a nest box, be sure to also provide lots of willow twigs, palm fronds, or other nesting materials as they will build a small nest of their own inside of the nest box.

Variety of babies — Courtesy Manny Berdecia. Separate easy is a girl – firm is a boy. This first aqua mutation in roseicolliss appeared in the early 60s in The Netherlands, in A. These are aqua and turquoise. Most are kept in pairs to satisfy their considerable need for constant companionship, mutual preening, and socialization.

A wonder bluu happened for sure. Now we know what we are dealing with and we realise that we are working with true mutations.

This intermediate colour, when combining two recessive mutations, proves that both mutations are alleles of each other.

If you have a tame pet that is kept in a small cage, it needs to be let out for extended periods to fly about. Data provided by GBIF. Instead, it is caused by the structure of the feather.

Young fischeri — Courtesy Fabio Tarazona. Roseicollis Lutino — Courtesy Didier Mervilde. To get a blue bird in lovebirds we need a feather of the structural type and a mutation that blocks the yellow psittacin pigment completely.

Serje they make a very fine and affectionate pet when hand-raised, they will need a lot of attention if kept singly. Yellowfeathered fischeri — Courtesy Refugio Cortes.
