Two inventors have developed a flying robotic bird of prey designed to scare off pigeons and seagulls by swooping in on their territory.

Bob McIntyre, 59, and Allan Davie, 60, developed the fibreglass peregrine falcon, which can move its head and call like a real bird, to work alongside an earlier, non-flying model.

The first bird, Robop, was launched last year and the inventors hope its sibling will work alongside it to scare more birds away from farmland and fish ponds.
