A wing-clipped Meyer's parrot perching on a drawer handle. While clipping is endorsed by some avian veterinarians, others oppose it. [7]By restricting flight, wing clipping may help prevent indoor birds from risking injury from ceiling fans or flying into large windows, but no evidence shows that clipped birds are safer than full-winged ones, only that clipped birds are subject to different ...

Green Clearwinged (a.k.a. Yellow Wing) and Dominant Grey-Factor appear in Australia. Both the NSL & the SL Lutino gene occurred in England and continental Europe. Three Opaline mutations occurred. An Opaline Green hen was captured in the wild and sold to S. Terril in Adelaide.
The double-factor Dominant Clearbody, with two Dominant Clearbody alleles, is believed to have a clearer body and darker wing markings than the single-factor Dominant Clearbody. The Dominant Clearbody gene is located on one of the autosomal chromosomes. There is no known linkage of this gene with any other mutation.
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. Such patches are devoid of the black melanin pigment and show just the ground colour—yellow in green-series birds and white in blue-series. The remainder of the body is coloured normally.
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 variety has normal wing marking in grey-black, off-white to grey flights, a tail rather lighter than usual, and normal violet cheek patches. The appearance is rather similar to the Dominant (Easley) Clearbody , but the normally coloured cheek patches distinguish the Sex-linked (Texas) Clearbody.
