when birds fly into windows

Unfortunately, several hundred million birds are killed each year as a result of collisions with windows.

Birds of all shapes and sizes travel at speeds high enough that a window collision almost always proves fatal. Birds that survive immediate impact are stunned and often fall prey to predators, like domestic cats, soon after a collision.

Why Birds Collide With Windows

Daytime and nighttime window collisions are the two primary categories. Birds collide with windows during the daytime because they can see vegetation or potted plants on the other side of the glass, or they can see reflections of the vegetation. Most songbirds and other nocturnal migrants crash at night when they fly into illuminated windows.

For reasons not entirely understood, lights divert nocturnal migrants from their original path, especially in low-ceiling or foggy conditions. In the lighted area, they mill about, sometimes colliding with one another or the lighted structure. As a subsequent hazard, migrants drawn off course by urban lighting may roost safely nearby, only to become vulnerable to daytime reflections in windows the following day. The BirdCast project and the Fatal Light Awareness Program have more about this problem.

One more reason is that birds occasionally target their reflections in windows. When territoriality is high in the spring, this occurs most frequently. Despite the fact that it may irritate the homeowner, the bird’s survival is rarely in danger. The majority of the solutions listed below for window strikes also address the issue of birds attacking reflections.

New Homes and Remodels

  • Install exterior shutters, and when you’re not in the space or utilizing the light or view, keep them closed. (These can be huge energy savers, too!).
  • To prevent sunlight from reflecting off of windows, install awnings or external sun shades. Remote controlled shades are available.
  • When installing new windows or building new structures, take into consideration windows that have a screen covering the entire exterior of the glass.
  • Install vertical blinds inside, and only partially open the slats.
  • Avoid visual paths to sky and greenery. The picture window’s opposite wall may have bright windows that create the appearance of an open path to the other side. Sometimes this can be resolved by closing a door between rooms or the shade on a window.

Lights Out initiatives are gaining ground in U. S. cities including Dallas, Houston, Philadelphia, and New York. Particularly hazardous is the all-night radiance of cityscapes, office buildings, and streetlights, which can divert migratory birds from their intended path, prolong their journey, and increase their risk of being struck by windows. A couple of fairly easy solutions to lessen the issue of artificial light at night are turning off unnecessary lights and installing downward-facing lighting. Using any of the aforementioned preventative measures against window collisions is still a good idea, especially for homeowners.

How to Help a Window Collision Victim

The best course of action for a bird that has struck a window is to seek immediate assistance from a wildlife rehabilitation center. Victims of window collisions may experience discomfort and internal injuries that are initially invisible but get worse over time. If left alone, they are susceptible to predators and foot traffic. Here’s what to do if you discover a bird unconscious following a window collision:

  • Try to capture and contain it. Approaching from behind, gently cover the bird with both hands The bird may flutter or call out—don’t be startled. Because small birds are so delicate, avoid wrapping your fingers or hand tightly around their body; instead, hold the bird firmly but gently.
  • Locate a suitable container that the bird can grip, like a small cardboard box lined with tissue paper or paper towels, or an unwaxed paper bag. The closed container should be placed away from kids and pets in a warm, quiet, and dark area.
  • As soon as the bird is inside the container, do not handle, feed, or water it. Keep in mind that wild birds may view humans as predators, so avoid causing stress to the bird.
  • Use this online directory to locate a rehabber in your area, then get in touch with them for more information. Inform the wildlife rehabilitation center if you are unable to relocate the bird, and they might be able to provide you with other options.
  • If the facility gives you the go-ahead to attempt releasing the bird, take it to a wooded area far from any buildings, or another habitat suitable for the species. Keep a safe distance from any trees or other vegetation before releasing the bird so you can evaluate its flight. Slowly open the top of the bag or box while pointing it toward any vegetation. If the bird has trouble flying, attempt to re-capture it and get in touch with the wildlife rehabilitation center for additional advice.
