Wow! This is amaaaazing:
The populations of falcons, kites and eagles have increased sharply in the wake of reintroduction programmes and improvements in their environments.
But now the Royal Society for the Protection of Birds (RSPB) has discovered that their success is leading to a decline in ground nesting birds such as the grey partridge, one of the most endangered birds in the UK, the capercaillie, the black grouse and its red cousin.
Waders such as the curlew, lapwing and golden plover are also at greater risk.
Stunning, eh? Increase the number of predators and the prey species are at greater risk. Who would have thought it?
