in occurrences. This is particularly important for areas like glazed corners and fly-through conditions, where birds are more likely to collide with glass due to reflections or transparency. [54]
Experts consider the material threat factor a prescriptive criteria for designing bird-friendly buildings. Therefore, no tradeoffs are allowed when assessing the façade materials.
