Gently Tapping

Sometimes human inventions can create a whole new set of problems for birds. Take windows, for example. Once upon a time a pair of cardinals could settle down, raise a family, send their young off to find a nice spot in neighboring yard, and spend a peaceful winter feeding on berries and seeds. Then came multi-story houses and buildings with windows everywhere, peeking out at shrubs and trees on all sides. Where’s a bird to go to be alone?

It was inevitable that our need to see them and their need for privacy would create a conflict – and danger of head-on flight collisions, too. But one occasional result is window tapping. It is clearly a territorial behavior but not an aggressive one. Sometimes, during breeding season, robins, cardinals and other birds will see their reflections on shiny objects and begin breast-beating attacks. Window tapping is much more benign. The birds just tap away, perhaps frustrated and confused, sometimes alone, sometimes in pairs. Perhaps they think they are challenging strangers, but, since their hormones may not have kicked in yet, the interaction is less intense. Encounters with reflected competitors seldom do any damage to the birds or to the windows. But regardless of cause, window tapping can become annoying to humans who listen, day after day, until we begin to twitch a bit in anticipation of the next go-round. Sometimes, placing (on outside surfaces which create reflections) strips of Mylar, fabric or other moving objects will distort the bird’s image enough to solve the problem. Sometimes it takes more direct intervention – opening the window or (gently) tapping on your side of the pane. If the window is near a favorite roosting spot, you might have to cover it (from the outside) until the bird moves on.

Mr. Poe notwithstanding, as long as there are windows and birds are territorial, there will be tapping evermore.
