I doubt it Neil, birds when moulting don't often throw the same feather in each wing at the same time. Birds can have a dominant wing, or a bias to swerve left or right, so maybe an 11 flighted bird would have that wing more dominant?NeilA wrote: Mon Dec 30, 2024 4:58 pmI wonder if 11 in one wing is a problem with balance when in flight rather than advantage compared to 11 in eachking wrote: Mon Dec 30, 2024 4:47 pm 11 flighted birds normally only have the extra feather in one wing. I don't think it's an advantage in any way, just a trait in some families.
Although when having a dropper it's always best having only one wing cut down, as birds with both sides cut can still get up and fly.
