Others refuse culls of corvidae, now with greater numbers than any time in History, which results in many tens of millions of bird deaths annually. In areas where songbirds struggle - some advocate the restoration of predators which have not been seen on our shores for many hundreds of years.
Goshawks, as one example, have been reintroduced to the UK after extinction in Tudor times!
Pesticides have long been a problem - as have domestic cats which do not wear collars with a bell attached. The problems of pesticides are, however, less than they have been over many generations.
Soft-hearted care of wildlife is a curse. Where man is involved and a major problem to wildlife - proper, tough management of situations need to be implemented.
