Abstract
Previous work has indicated that the woodpigeon ( Columba palumbus) uses a visual alarm signal based upon the exposure of white wing markings. Field trials were conducted over three winters to see whether woodpigeon corpses or models of woodpigeons, both clearly showing the wing marks, could reduce woodpigeon damage to clover. The first trial demonstrated that real woodpigeon bodies with outstretched wings provided significant protection over a 9-week period but also revealed that crude woodpigeon silhouettes were not repellent. The second trial showed that pairs of wings were as effective as whole bodies and that three-dimensional, lifelike models were as efficient as corpses. The final experiment revealed that the real bodies or wings have to be in good condition to remain effective. Raising them above the ground increases their effectiveness.
