He mentions Little Tern colonies in Norfolk being decimated by Kestrels. Closer to home the same thing happened at Beacon Ponds, Spurn this year. Fencing was generously provided to protect against ground predators but aerial threats can't be stopped.
Predation is a natural phenomenon and has obviously occurred since time immemorial BUT my question is... does this make it right in all cases?
A rare breeder like Little Tern needs more "help" in my humble opinion. (Nearly) every year the young get massacred despite the best efforts of dedicated volunteers and sponsors.
I don't know the breeding success rate of this species in recent years nationally, but it can't be great.
Maybe I'm wrong (I often am!) but surely the odd predator could at least be "re-located"? This species needs OUR help...NOW!!!
