So, I was engaging in the very dangerous pastime of looking at budgies for sale online (just window shopping ) and found this little bird.
Gorgeous colouring but what is going on with the extra couple of feathers at the front of each wing?
Is just just a fluke or a recognised mutation such as the crested budgies?
Is this likely to change at all when the bird moults?
Is it associated with any other conditions?
This actually look like one of the feathers of the alula (a bird's thumb) which is not being held normally. These feathers on the thumb are, in flight, used to control maneuvering.
They're often not seen but depending on what happened to the bird before the photo could be related to how it was handled, causing displacement. Its normal placement, when the wing is folded, is mostly hidden. Certainly could be related to specific genes, just like most genetic problems in domesticated animals (including budgies). They're not extra feathers though....budgies do have thumbs, like most birds!
