Grizzle Lovebirds: a few years ago, this breed
appeared on the Agapornis roseicollis and became very crowded when senior
Agapornis breeder David Branigan first uploaded a photo of the bird.
Some
people call him a Grizzle, and others a Grizzly.
Grizzle lovebird Is a phenotype that indicates all or some parts of the feathers have strokes of another color. Sometimes, it is characterized only by spotting spots on certain parts of the feathers.
Grizzle is common in pigeons, dove, and their families with a wide variety. But only recently has it been found in parrots as before in Indian ring necks.
In pigeon species, Grizzle is an Incomplete Dominant mutation; this trait's inheritance has been recognized for many years.
Later, the grizzle lovebird also appeared on the Agapornis Fischer; you can see
it in the posts of some Agapornis breeders on social media.
At
first glance, it looks like a pied mutation in the previous Agapornis, but in
the Grizzle, the difference lies in the random pigment patches on certain
parts of the feathers.
It generally occurs in the wing feathers and
head and in all parts of the feathers.
Some people strongly believe
Grizzle is a new mutation in Agapornis, adding confidence when they find
chicks that resemble grizzle parents in breeding test pairs.
" Came to the conclusion that the grizzle can be inherited."
They need to learn more about the trait inheritance mode of the Grizzle they have.
Characteristics of Grizzle's lovebirds
Grizzle Lovebirds are still part of the half-sider, birds that usually have two or more aspects of the plumage opposite in color.
This is not without reason; you can see the half-sider in the rows of melanin mutations. Let's take an example of the Lutino Mutation.
Lutino is generally yellow in most feathers. When the phenotype is abnormal and becomes a Lutino Half Sider, they leave a specific part of the feathers that still have pigment.
Some entire form blocks and some form partial like strokes on feathers; you can see them in the pictures I included.
So broadly, half-siders not only form two opposite blocks but can also form from small parts of the opposite colored feathers.
Feather Condition of Grizzle Lovebirds
It is the "Barbule" part of the fur structure that there may be differences in
color pigmentation crosswise so that what is visible to the eye is the effect
of the strokes of the color of the grizzle lovebirds.
Phenotype Grizzle Fischer
There may also be influences from Dominant Pied, Dominant Edged, or Opaline mutations. Because some Grizzle emerged from Opaline's non-Grizzle parents.
However, Grizzle can also be an actual Mutation in Agapornis Fischer.
It still needs a breeding test until the conclusion that the Grizzle is Dominant, Recessive, Incomplete Dominant, or multi-factor only.
This is a little tricky, considering that half-sider Agapornis can also be inherited just as much as existing mutations, although their acquisition is unpredictable.
Even from two halfsider parents, they sometimes find regular chicks.
If the Grizzle Lovebird is a natural mutation, then it should be that M.O.I is as dominant as the Grizzle pigeon.
However, the inheritance on the results of the crossing could be more consistent in getting Grizzle chicks. In that case, they are inevitably multi-factorial, as in the case of half-sider lovebirds.
