Wing clipping is the process of trimming a bird's primary wing feathers or remiges so that it is not fully flight-capable, until it moults, sheds the cut feathers, and grows new ones. This procedure is usually carried out by avian veterinarians, breeders, or the bird's owners, and primarily on pet birds like parrots.
The Clearwing Skyblue is similar but with a blue body and white wings. The body colour is a little brighter in tone than the corresponding normal. [1] The wings and mask carry pale grey shadows of the normal markings and spots. In the best show birds these are quite faint, but nevertheless are still clearly visible.
In the non-Opaline the wings show dark grey or black markings over a yellow or white ground, but in the Opaline the ends of the barbs of the wing coverts assume the same colour as the body, rather than the ground colour. This suffusion of body colour in the wings produces the opalescent effect which gave the mutation its name.
All pied budgerigars are characterised by having irregular patches of completely clear feathers appearing anywhere in the body, head or wings. These clear feathers are pure white in blue-series birds and yellow in birds of the green series. Such patches are completely devoid of black melanin pigment. The remainder of the body is coloured normally.
Cut a piece of kitchen twine and tie the legs together at the drumstick ends. Take another piece of twine, loop it under the bird's body across the tucked wings, and tie securely.
The genetics of the several Yellowface mutations and their relation to the Blue mutation are not yet fully and definitively understood. [4] [5]Much confusion and misunderstanding have arisen because the popular names given to these mutations are misleading.
The body colour of the Greywing variety is about half the intensity of the corresponding normal variety, and the wing, head and neck markings are similarly reduced in intensity from black to mid-grey. [1] The spots are grey and the cheek patches are pale violet. The tail feathers are grey with a bluish tinge.
I J J Symes gave a description [10] of what he called "the brown factor" in this bird, saying the wing markings varied from raw umber to burnt sienna. A D Simms, of Potter's Bar, also in Middlesex at the time, paired together several Dark Green split greywing siblings in 1931 bred from an Olive cock and a Greywing Light Green hen. Among other ...
