In Banna Garden, birds are rich in resources, and a lot of glass is installed on the surface of the building, so birds often hit the glass to death and cause injuries. Although birds have extraordinary eyesight, it is difficult to find the existence of glass. On the contrary, when they see the reflection of the sky and plants on the glass, they will mistake it for a safe place, especially when they are frightened or threatened. At night, decorative lights near the glass will disorientate migrating birds, causing them to collide with skyscrapers, office buildings or other glass decorated with lights. Large glass and corner glass are the most vulnerable to impact, but even small glass can cause fatal impact. Although sometimes a strong impact will kill the bird on the spot, usually, the bird looks dizzy and will gradually recover and fly away. However, these birds will have sequelae of congestion or brain swelling, which usually leads to death. Birds that are hit will also lose their flying skills and ability to tell directions, and they are more likely to be hunted by other animals (such as raptors or cats). The reflection on the glass will make the bird misjudge its position. How to prevent birds from hitting the glass? There are many ways to reduce or even completely avoid birds hitting the glass. The best strategy is to use multiple methods at the same time, so that birds can see the glass clearly and avoid it. Indoor solutions 1. Install curtains or blinds indoors to make the glass as non-reflective as possible. If the angle is correct, these decorations will not affect the indoor light or the scenery outside the window, but they are very important to birds. Please try to remove the plants placed in front of the window, so that birds will not think it is a shelter or food source. Plants should be placed where birds can't see them from the outside. 3. Installing patterned glass can reduce the reflective area. 4. Hang thin curtains on large glass to reduce reflection. Tighten the curtains. These curtains will not affect the visibility, but can effectively reduce the impact of birds on the glass. Outdoor solutions 1. You can add some decorations to the windows to reduce the reflection. Such as putting up pictures of birds of prey or other decorations. 2. Install a single-sided transparent film similar to a car window, which can be seen from the inside out and opaque from the outside in. 3. Installing sunshade or shading cloth outside the window can not only reduce reflection, but also save energy. 4. Place a certain height of green plants outside the glass, and the birds will stay as shelter, so that the birds will stop on these plants before trying to pass through the glass, and even if the birds take off again and hit the glass, they will not be injured because of insufficient speed.
