Recently, at the end the day, I noticed a departing greenhouse worker remove a plastic nursery pot from each rear view mirror and stow them in his tool box. Old memories awakened as I asked him what was up with his mirrors. “That damn bird!” was his answer, and I knew a red bird had found his truck.
For as long as our greenhouses have been here, people working there have parked outside. And just as long, cardinals have found themselves irresistible in our rear view mirrors. Or maybe they see a rival that s equally matched? Whatever they see, it causes them to stay a long time and return frequently. And while they are looking deeply into the mirror, they are also digesting and leaving their droppings in large quantities. The mess is even worse when car windows are left down, then the inside is fouled too.
Over the years, employees have tried various methods for stopping the cardinals from soiling their cars. Socks, hats, and various other items have been selected. But the best I have seen yet is an old nursery pot. We do try and cooperate with nature, but do not feel we need to share our vehicles with the birds.
