Urban Jungle: Seagulls are leaving their traditional habitats and moving into towns to , both coastal and inland, where they are thriving on the ready supply of food left on rubbish dumps and dropped in the streets by visitors and fast-food customers. Dramatic increases in urban numbers of these aggressive , sometimes oversized, birds have been parallelled by growing attacks on humans, domestic animals and other birds. Seagulls are particularly aggressive during their breeding season, but, their culling is environmentally prohibited.
