Early breeding results showed this Grey to be a Dark Grey (SF)/dilute, and Mrs Harrison went on to establish a substantial strain of Greys from this bird. [ 2 ] [ 3 ] In 1936, it was reported [ 4 ] that W F Shepherd of Kew, Victoria, also had Greys which he obtained from a colony breeder, and a Grey was also bred independently by R Hancock of ...

The Australian budgerigar, or shell parakeet, is a popular pet and the most common parakeet. Parakeets comprise about 115 species of birds that are seed-eating parrots of small size, slender build, and long, tapering tails. [citation needed] The Australian budgerigar, also known as "budgie", Melopsittacus undulatus, is probably the most common ...
Also defined: seabird colony; breeding colony; communal roost; heronries; rookery. A large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony.
The wildtype (natural-coloured or wild occurring) budgerigar's color is called Lightgreen. The feathers of most parrot species, including budgerigars, contain both a black type of melanin named eumelanin along with a basic yellow pigment named psittacofulvin (psittacin for short).
The loci of the Dark budgerigar mutation and the Blue allelic series are situated on the same autosome, so the Dark mutation is linked to the Blue allelic series (see genetic linkage). The cross-over value (COV) or recombination frequency between the Dark and Blue loci is commonly stated to be about 14%, [ 6 ] but some experiments have found ...
When pure-breeding (homozygous) Greywings are paired with pure-breeding Clearwings the resulting offspring, known as Full-bodied Greywings, are quite distinct in appearance from both parents. They have a body colour almost as deep as the corresponding normal variety and with the rich sheen of the Clearwing, but with medium grey markings ...
A third appearance of the Ino mutation occurred in Germany around 1933, when Mr Kuhlewein bred a Lutino [4] hen in an uncontrolled breeding flight. [7] This strain was also established. Other Ino mutations also appeared in Europe in the early 1930s, and several British fanciers, including Walter Higham, [ 4 ] Scott and Camplin, and Tod Boyd ...
