According to a survey by Opinions Matters, in association with London Wildcare Trust,  the most unpopular animal in the garden is the magpie.

(Almost 29 per cent of British people surveyed believe they are a menace that destroy the nests of other birds.   However, according to the RSPB old magpie nests are often used by protected species, such as long-eared owls in rural areas and blackbirds in suburban areas, so it’s swings and roundabouts really.)
