Wing trimming details.

Wing trimming details.

• A. All wing feathers
• B. Tail feathers
• C. None
• D. First 10 primary feathers of one wing

Answer: (D)

Wing trimming works by shortening the flight feathers—the ones that actually generate lift—without removing the entire wing structure. The standard approach is to trim the first ten primary feathers on a single wing. This reduces the bird’s lift enough to prevent sustained flight while keeping other feathers intact so the bird retains some balance and control for gentle landings and maneuvering. Trimming only one wing creates asymmetry, making it difficult for the bird to fly away and helping prevent escapes, yet still allows some steering and landing ability. Trimming all wing feathers would remove too much lift and could cause trouble with thermoregulation and overall balance, while trimming tail feathers targets steering rather than lift. Trimming none would leave the bird fully capable of flight.
