NR and CATS

[NorthernRaider]

I remember also either reading or hearing about some nature reserve wardens along the Tees in the late 70s who noticed that in one particular area on one side of the river ( it MAY have been old Thornaby but I honestly cannot be sure) these folks noticed suddenly how completely silent the area was at dawn and dusk, it was as if no birds lived there, turned out they were correct, the near by allotments had a small collection of old outhouses and sheds that were no longer used and almost completely overgrown. Feral domestic cats had set up home in the sheds and there was about 30 of them in total, they had wiped out most of the birds from nesting ducks, black birds, goslings, sparrows, finches etc along a sizable chunk of the river bank.

Aha you just answered a question for me there BP, I was wondering why the land fills near Hartlepool had big nets over them, I thought it was to stop litter blowing but I bet its to stop black headed gulls.
