Wouldn't recommend Aviator for a budgie, though. The straps are just too thick for their little bodies. Remember, ALL parts of a harness have to be proportional to the bird, not just the strap length. I do recommend Mini Wings, though, as all the harness parts are proportional to the budgie.In general budgies arenβt great with harnesses and walks, as stated above. But every bird is different so if the owner thinks their budgie will do fine, Iβd recommend the Mini Wings or Aviator harness.
