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.
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.
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.
Scheme of dorsoventral cut through a thorax segment with wings. a. wings b. joints c. dorsoventral muscles d. longitudinal muscle. Flapping counter-torque is a ubiquitous passive rotational damping effect in flapping flight that arises from world frame differences in the speed of flapping wings during turns. During a turns, flapping that is ...
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 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.
Pinioning is the act of surgically removing one pinion joint, the joint of a bird's wing farthest from the body, to prevent flight. Pinioning is often done to waterfowl and poultry. It is not typically done to companion bird species such as parrots. This practice is unnecessary and restricted in many countries.
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.
