The gulls who crave crisps Gulls are well-known for scavenging on our leftovers, and it turns out they’re happy to fly long distances to do this. Many gulls from a Belgian breeding colony took excursions to cities in the UK, but researchers spotted that they also headed south to Mouscron, a city on the French border 65 kilometres away where the birds were bingeing on discarded potatoes at the Roger & Roger crisp factory. Orange lines are from a gull named Eric, red are Roxanne and purple Harry. All other gulls are blue. Source: Lifewatch INBO
