Birds hitting windows

Birds hitting windows is a common problem. Depending on the lighting, a window – even a relatively small one – can behave like a mirror. A bird in a hurry, such as one threatened, can mistake the window for open spaces.

With most household windows and doors, a crash happens only rarely, if ever. However, if you have windows – particularly picture windows – that birds regularly collide with, consider a product like Window Alert. These are plastic decals that are virtually invisible to humans on the inside of the house, but are very visible to birds on the outside.

According to the manufacturer, “The decal contains a component which brilliantly reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but glows like a stoplight for birds.”

The product functions sort of like those advertising coatings that you see on commercial vans and city buses that cover not only the metal surfaces of the vehicle but also the windows. People inside can see out perfectly well, though from the outside the window looks like part of a sign.

The decals, which come in various shapes including leaves and snowflakes, are sold in many stores that serve bird watchers and feeders. For more information, see windowalert.com.
