Ever wonder why birds seem to throw themselves at your window? You can help prevent window strikes and make your windows safer.
Birds such as cardinals and robins will dash repeatedly at their reflections in windows. This is usually because the individual bird, usually a male, mistakenly perceives another bird in the reflection of the window. It is territorial behavior for the bird to fight off the ‘intruder”. This behavior, if continued over a period of weeks or even an entire season, can be annoying to people, but is usually not fatal to the bird. On the other hand, when a bird strikes a window in free-flight, it does so with such velocity that the results are significantly more serious.
Sometimes the bird is merely stunned or sustains superficial injuries from which it may recover, but in over half of all recorded incidents the impact results in death. This is most common during spring and fall migration, but can happen at other times of the year. Birds cannot readily distinguish the presence of a pane of transparent glass from an unobstructed space or passageway. Glass will reflect the most when it is darker inside than it is outside.
Many people are unaware that birds are being killed at their windows because the victims are small, frequently fall behind shrubbery, and more often than not are eaten by predators. Some birds bang into windows because they think they see another bird in their territory, some birds fly into windows because they don’t see the window. Other birds fly into windows because they are being chased by predators. Whatever the reason, you can make your windows safer.
