Wing clipping is the process of trimming a bird's primary wing feathers or remiges so that it is not fully flight-capable, until it moults, sheds the cut feathers and grows new ones.
This procedure is usually carried out by avian veterinarians, breeders, or the bird's owners, and primarily on pet birds like parrots. Different techniques involve varying number of feathers cut and the amount of feather length left behind. These methods can have potential physical and psychological effects on birds, such as injury from falls, distress, and behavioral changes.
Molting in birds with clipped wings can expose their growing blood feathers, making them vulnerable to damage and excessive bleeding. Moreover, wing-clipping can disrupt the birds' natural flight and landing behavior, potentially leading to crashes at higher speeds than unclipped birds.
Despite this, it is suggested that young birds be allowed to learn to fly properly before any wing clipping occurs. This will enable them to remain more confident and active and learn crucial landing skills.
The practice of wing clipping is controversial, with some avian veterinarians endorsing it while others oppose it. While clipping can prevent indoor accidents like hitting ceiling fans or windows, it also restricts the bird's mobility, exercise, and ability to escape fearful situations. Some argue it's a necessary safety practice, particularly for climbing birds, while others feel it's cruel and unnecessary if birds can be trained to respond to flight commands. The practice appears more common in American bird care literature than in British sources.
