Biccylova. At the last census by the BTO, there were about 190,000 breeding pairs of sparrowhawks in the UK. Contrast that with over 9 million cats.
As a birdwatcher, I think the controls on pest species shouldn't have been lifted. Research on keepered land has shown that it benefits song bird populations.
However, birds of prey populations have plummeted, especially over grouse moors, take hen harriers for example. Golden eagles are struggling in Scotland, peregrines and goshawks are nearly extinct in the Dark Peak. There is no coincidence that these areas are heavily keepered shooting estates.
