By feeding them, you could end up encouraging hundreds of them to turn up each morning expecting grub. What happens then? If you don’t bring enough food for everyone, do the unfed strike back with their phaser beams and photon torpedoes?
[ When the feeding of pigeons was banned – with the threat of a £50 fine – in Trafalgar Square in London, in 2002, the number of pigeons fell from 4,000 on an average lunchtime to 200. It wasn’t a matter of pigeon starvation/die-off. They were just going elsewhere to get food.]
