What can a screen perch do if not properly designed?

A poorly designed screen perch can lead to damage to the bird's feathers due to inadequate surface material or inappropriate spacing. If the perch surface is rough or has sharp edges, it can cause wear and tear on the feathers as the bird attempts to balance or adjust its position. This can result in feather breakage or abrasion, leading to potential health issues for the bird.

Proper design of a screen perch is crucial for the overall well-being of the bird, as it needs to ensure comfort and safe perching without harming the feathers. This aspect of perch design is critical in falconry, where bird care significantly impacts training success and overall health.
