How to Keep Birds From Flying Into Windows
Birds, with their vibrant presence and crucial role in ecosystems, are a natural wonder. However, the built environment poses significant threats to them, particularly in the form of windows. Birds often collide with windows, leading to injury or death, but thankfully, there are simple measures that can be taken to prevent these collisions.
The Scope of the Problem
According to Chatelaine, over a billion birds die each year in North America alone due to window collisions. Birds, unable to see glass, often mistake reflections of the sky or trees for actual open space. Additionally, they might perceive indoor plants or the other side of a window as a place to perch. Birds also sometimes attack their reflections, mistaking them for rival birds.
Dr. Christine Sheppard of the American Bird Conservancy explained to Chatelaine that birds are incapable of learning the concept of glass. They cannot differentiate between a reflection and actual habitat, making it crucial to take preventative steps.
Effective Prevention Strategies
Identify Problematic Windows
First, determine which windows are the most hazardous for birds by observing from the outside. Identify windows that are opaque in sunlight, reflective, or transparent, and then take action to make them more bird-friendly.
Applying Stripes and Dots
Creating visible patterns on windows can help birds perceive them as solid objects. Here are a few methods to achieve this:
- Tempera Paint: Use weatherproof, but removable tempera paint to draw patterns on windows.
- Decals and Stickers: Place decals or sticky objects close together on the exterior surface of the window.
- Patterned Tape: Apply specialized tape with stripes or dots to break up the reflective surface.
- Zen Curtains: Install vertically hanging ropes closely spaced together on the window.
- Window Screens: Use window screens to make windows more visible to birds.
These methods disrupt the reflection and transparency of windows, helping birds recognize them as barriers.
