The bird appears unclipped when at rest and so the cosmetic appearance is very good. The bird is still able to provide some lift when flying so that self-trauma is reduced when launching itself off a cage. We always advise a test flight at home to assess the birds flying ability. If the bird still is too mobile for your liking, we remove further feathers free of charge. The feathers are clipped high up so that the smaller wing feathers cover the stumps left behind to reduce trauma and annoyance to reduce the risk of feather plucking.
Wing clipping is a technique to be perfected.
Do not attempt it yourself - take the bird to an Avian veterinarian.
