The green wild type fisheri.
The Green wild-type Fischer's Lovebird, scientifically known
as *Agapornis fischeri*, is a small, brightly colored parrot native to
north-central Tanzania. These lovebirds have a predominantly green plumage with
a golden yellow to orange neck, which deepens into a vibrant orange-red on the
face. The top of their head is olive green, and they have a distinctive red
beak. Additionally, they may exhibit blue or purple plumage on their tails.
Fischer's Lovebirds measure about 12 to 15 centimeters in
height, with a wingspan of up to 9 centimeters, and can weigh up to 58 grams.
They typically live in grasslands, semi-arid woodlands, and savannas, and are
known to nest in natural cavities in trees, rocks, or buildings. Their diet is
mainly granivorous, although they can sometimes be found feeding on fruits and
crops, which occasionally causes them to be considered pests by farmers【31†source】【32†source】.

Pairing
and Genetics of Fischer's Lovebirds.
When breeding Fischer's Lovebirds, understanding the
genetics and potential outcomes of pairings is crucial. Here are details on
pairing and the genetic principles involved, specifically for Green wild-type
Fischer's Lovebirds and their mutations, based on the insights from the
"Lovebirds Compendium" by Dirk Van den Abeele and other genetic
principles.
1.Basic
Genetics Principles:
Dominant and Recessive Genes:
In lovebirds, certain traits are dominant while others are
recessive. Dominant traits will appear in the phenotype even if only one copy
of the gene is present, whereas recessive traits require two copies to be
expressed.
Autosomal and Sex-Linked Traits:
Autosomal traits are inherited through non-sex chromosomes,
while sex-linked traits are carried on sex chromosomes, affecting the
inheritance patterns differently between males and females.
2.Green
Wild-Type Fischer's Lovebird:
Appearance:
Predominantly green plumage with a golden-yellow to orange
neck, and a red beak.
Genotype:
The wild-type green coloration is dominant (G).
3.Common
Mutations in Fischer's Lovebirds:
Opaline:
A recessive mutation affecting feather coloration. Birds
must inherit two copies of the opaline gene to express the trait (o/o).
Dark Factor:
A semi-dominant trait that affects the shade of the bird’s
color. Birds can have no dark factors (light green), one dark factor (dark
green, DF), or two dark factors (olive green, DD).
Dilute:
A recessive mutation that lightens the color of the plumage
(d/d).
4.Pairing
Outcomes:
A.Green (Wild-Type) × Opaline:
Genotype of Parents: G/G × o/o
Offspring: All offspring will be Green split for Opaline
(G/o).
B.Green (Wild-Type) × Dark Factor:
Genotype of Parents:
G/G
× G/DF or G/DD
Offspring:
- If paired with a
single dark factor (G/DF): 50% Green, 50% Dark Gr/een.
- If paired with a
double dark factor (GDD):
100% Dark Green.
C.Opaline × Dark Factor:
Genotype of Parents:
o/o × G/DF
or G/DD
Offspring:
- If paired with a
single dark factor (G/DF):
All offspring will be Green split for Opaline and Dark Factor (G/o, G/DF).
- If paired with a
double dark factor (G/DD):
All offspring will be Dark Green split for Opaline (G/o, G/DD).
D.Green (Wild-Type) × Dilute:
Genotype of Parents:
G/G
× d/d
Offspring:
All offspring will be Green split for Dilute (G/d).
5.Advanced
Pairing Examples:
A.Opaline × Dilute:
Genotype of Parents:
o/o × d/d
Offspring:
All offspring will be Green split for Opaline and Dilute
(G/o, G/d).
B.Double Mutation Pairing (Opaline Dilute × Dark

Genotype of Parents:
o/o d/d × G/DF
or G/DD
Offspring:
- With a single dark
factor (G/DF): Green
split for Opaline, Dilute, and Dark Factor (G/o d/d DF).

Blue fisheri.
The production and pairing of Blue Fischer's Lovebirds are
complex and involve understanding their genetic mutations. Here’s a detailed
look based on Dirk Van den Abeele's *Lovebirds Compendium* and other sources:
Blue
Fischer's Lovebird Production.
Blue Fischer's Lovebirds are characterized by:
- Bright blue back, tail, and chest
- Pale grey top of the head
- White remainder of the head
- Pale pink beak
Genetic
Inheritance.
Blue Fischer’s Lovebirds inherit their color through an
autosomal recessive gene. When breeding for blue mutation, the following
outcomes are observed:
Blue x Blue:
All offspring will be blue.
Blue x Green:
All offspring will be
green, split for blue (carrying the blue gene).
Green/Blue x Blue:
There is a 50% chance of blue offspring and 50% chance of
green split for blue.
Green/Blue x Green/Blue:
There
is a 25% chance of blue, 50% chance of green split for blue, and 25% chance of
green.
Complex
Pairings.
When Blue Fischer's Lovebirds are paired with other
mutations like aqua or turquoise, the results vary:
Aqua x Blue:
Produces intermediate colors that suggest alleles of the
same gene.
Aqua x Turquoise:
Results in a mixed color phenotype, termed AquaTurquoise,
indicating a combination of alleles of the same gene【42†source】【43†source】.
Practical
Breeding Tips
For optimal breeding results:
- Pairing blue with blue guarantees all blue offspring.
- Introducing a blue mutation with a wild type (green)
ensures the offspring carry the blue gene, useful for future breeding programs.
- Understanding the genetic combinations and possible
outcomes helps in planning and achieving desired color mutations.
This detailed understanding of genetic principles and
breeding outcomes is crucial for breeders aiming to produce specific color
mutations in Fischer's Lovebirds【44†source】【41†source】.

Compendium*.
Detailed
Genetics and Pairing for Blue Fischer's Lovebirds
Basic Understanding
The Blue mutation in Fischer’s Lovebirds (*Agapornis
fischeri*) is a recessive autosomal trait, which means a bird must inherit two
copies of the blue gene (one from each parent) to express the blue phenotype.
The blue mutation reduces the yellow pigments, resulting in a bird with blue
plumage.
Genetic
Notation
B = Wild-type (green) allele.
b = Blue allele.
A bird with genotype **BB** or **Bb** will appear green,
while a bird with genotype **bb** will appear blue.
Pairing
Outcomes

Genotypes of Parents:

Offspring Genotype:
50% bb, 50% Bb
Offspring Phenotype:
50% Blue, 50% Green (split for blue)
Green Split Blue x Green Split Blue.
Genotypes of Parents:
Bb x Bb
Offspring Genotype:
25% BB, 50% Bb, 25% bb
Offspring Phenotype:
25% Green, 50% Green (split for blue), 25% Blue
Blue x Green (Wild-Type)
Genotypes of Parents:
bb x BB
Offspring Genotype:
100% Bb
Offspring Phenotype:
100% Green (split for blue)
Pairing
with Other Mutations
Blue x Aqua
- Aqua is another color mutation and behaves similarly in
terms of inheritance. When blue and aqua are crossed, intermediate colors may
result.
Blue x Turquoise
- Pairing blue with turquoise can produce a range of colors,
often intermediate, demonstrating the allelic interactions between these two
mutations.
Advanced
Pairings
Blue Opaline x Green
Genotypes of Parents:
bb (opaline) x BB
Offspring Genotype:
All offspring will be Bb (split for blue and opaline)
Offspring Phenotype:
All green but split for blue and opaline
Blue x Dilute
Genotypes of Parents:
bb x d/d
Offspring Genotype:
All offspring will be
green split for blue and dilute
Offspring Phenotype:
Green (split for blue and dilute)
Blue x Lutino
Genotypes of Parents:
bb x L/l (assuming Lutino is recessive and sex-linked)
Offspring Genotype:
Female offspring will be green split for blue and lutino;
male offspring will be split for blue, potentially exhibiting a variety of
intermediate phenotypes.
Breeding
Strategy
For breeders aiming to produce blue Fischer’s Lovebirds:
- Pairing two blue birds guarantees blue offspring.
- Pairing a blue bird with a green split for blue will yield
a mix of blue and green split for blue.
- Breeding green split for blue pairs can produce a variety
of outcomes, including blue, which helps maintain genetic diversity while still
producing the desired blue mutation.
Practical
Considerations
Understanding these genetic principles helps in planning
breeding strategies to achieve specific phenotypic outcomes. Careful selection
and knowledge of the birds’ genetic backgrounds are crucial for successful
breeding.
