A very good point - we do owe her a great deal.

In the early 70s when I left this island - there had not been any breeding Pergrine Falcons here since the late 1950s - despite many suitable sites.

I am pleased to report that there are now 5 sites occupied by breeding pairs. This must be good news - only qualified by the fact that the breeding success of coastal pairs is not that high.

Silent Spring was written only just in time - but the threat continues.
