Every year, there are nearly one billion deaths of migrating birds collide with windows and glass curtain walls. With the continuous increase using of glass curtain walls, the impact is becoming huge.
What’s the solution to protect migrating birds? Why is the normal glass dangerous to them? Let’s dive in.
Glass characteristics – why it is dangerous to birds
Three characteristics of glass make it dangerous to birds:
- Reflective: Especially in the daytime, the glass will reflect the normal scene, causing the bird to hit the glass.
- Transparency: Also at some time in the daytime, the glass is not so reflective, birds will try to pass through the glass.
- Beacon effect: Buildings with active lighting are particularly harmful to birds that are active at night, especially under rain or hazy conditions. Birds descend to a lower height to maintain their position, and they are attracted by the lights of buildings with tragic consequences.
The American Bird Conservation Association has researched and developed guidelines for glass designs to protect birds. These designs have been scientifically proven to be a visual deterrent. The bird anti-strike glass pattern is defined as a pair of horizontal elements (separated such as dots, lines, outlines, etc.) by no more than 2 inches with vertical elements separated by no more than 4 inches. Birds in flight see these visually and will avoid collision accidents.
Digital printed glass can protect birds
Digital printed glass provides unlimited design possibilities while protecting birds. This is a fast, accurate, and cost-effective solution, especially for graphics that contain more complex designs, more colors, and non-repetitive printing on the entire panel.
Studies have shown that birds can perceive colors, which means that colored and random patterns will greatly reduce the number of collisions. These inks can be applied to the inside of the glass (face 2), but printing on face 1 is still the most powerful solution.
Fortunately, the face 1 surface ink can also be used in the digital world, which allows us to print complex designs on the outer surface. Just like screen printing inks, this high-performance solution reduces glare and reflections on the glass, providing a safer barrier for birds. The design patterns are endless, and it is easy to adapt to the required standards.
