Doves and pigeons aren't very bright, are they? A pair of woodpigeons has made a nest in my garden - in the honeysuckle which grows up the side of a wooden arch. It's a frail plant, and the birds are fat and hefty. If they manage to incubate the eggs at all, the added weight of growing chicks is likely to send their ramshackle home to the ground. That's if a cat doesn't casually reach in to the low-hanging nest and remove the chicks.
