With all the attention paid to bird strikes in the air, it's easy to overlook the issue of birds' nests in our airplanes. For years, birds would ignore my Bonanza when performing their annual spring house hunting. But in the past couple of springs, the value of my rampside property seems to have escalated in their eyes. Location, location, location, I guess. This time of year, there always seem to be starlings hovering around with twigs and straw hanging from their beaks.
