A cull of crows and magpies is soon to be implemented at sites in England, Scotland and Wales. It is funded by the group, Songbird Survival, who blame Corvids for the decline in certain songbird populations, despite prior studies by the British Trust for Ornithology and the Royal Society for the protection of birds (RSBP). Both have exonerated Corvids as a cause for songbird decline.

The Royal Society for the protection of Birds believes the decrease in numbers of songbirds has been caused by the increase use of agricultural chemicals, the destruction of hedgerows and the loss of wild flowers which has led to a loss of nesting areas, lack of food for chicks, and lack of food in the winter. They found that songbird numbers were no different in places where there were many magpies from places where there were few.
