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.

I am delighted to join the Birdzilla team through this blog, sharing ideas and topics related to feeding and attracting wild birds in your backyard. Bird feeding is my life-long passion,  instilled by bird-feeding parents who raised me on an 80-acre farm in central Michigan.  After college, my wife and I served as U.S. Peace Corps Volunteer high-school teachers in Africa and then as staff members over an eight-year period.
Those wonderful times led to 30-years of bird-feeding leadership as founder of the Wild Bird Centers, franchising and supporting wild bird specialty stores across the country. I helped found the Bird Education Network and was a key financial supporter of PROJECT WILDBIRD, I currently serve as Executive Director of the National Bird-Feeding Society. Several years ago, I was asked to join “The Birder’s Team”, a working group of birding leaders selected by the National Wildlife Refuge System to recommend ways to better serve birders. millions of whom visit our extraordinary network of more than 500 Refuges. These “conservation jewels” actively protect critical habitat and conserve bird populations of all kinds. Most recently, I served as a judge to select the winning artist for the NWRS’ 2015 Duck Stamp Contest.

I now look forward to helping our readers experience the best our wonderful hobby offers. As I often say “The closer we live to each other, the closer we want to be to Nature.”
