Bird Feeding Tips
Tips on attracting and feeding backyard birds.
An Interesting Springtime Behavior
Every spring, we hear from readers dealing with birds attacking windows, car mirrors and other reflective surfaces. To their credit, these folks seem more concerned for the birds than personally irritated. Birds that engage in this aggressive behavior (often robins and cardinals) can injure themselves so why do they ram their heads, beaks and bodies against these shiny surfaces?
Simply put, these birds are responding to rising hormones. It is nesting season (or will soon be in your area) and birds are genetically wired to protect territories to assure that young produced are theirs to raise, Natural selection has always favored animals which are territorial and aggressive in defending food and other necessary resources.
These birds see their own reflections and believe they are seeing potential invaders. So they begin to furiously attack “the enemy.” They usually do not quit until they think they have won or until their mates have laid all their eggs. This is thought to triggers a reduction in hormone levels. Unfortunately for us, this can seem to take forever!
To help your birds, try eliminating the reflection. Cover the shiny surface with a paper sheet, newspaper or brown paper. Some folks have luck soaping their windows (outside surfaces only!). If this is not feasible, then wait, enjoy the moment and hope your bird will win the “battle” before hurting himself seriously.
