Why are vertical bars recommended over wire mesh on windows?

• A. Prevent feather damage
• B. Improve insulation
• C. Reduce costs
• D. Increase visibility

Answer: (A)

Vertical bars protect the bird’s feathers by reducing snagging and abrasion near windows. Wire mesh has many small openings that can catch or rub against feathers as a raptor moves or brushes past, leading to feather damage. Bars provide a barrier that blocks direct contact with the glass while presenting fewer snag points, still letting the bird see through. This focus on protecting plumage makes bars the better choice, whereas insulation, cost, or visibility are not the primary considerations here.
