Setback for Norfolk quarry bee-eaters

We had a problem at our Ringing Group's artificial Sand Martin "Bank" in 2018.  Although the breeding birds did not return that year, judicious use of humane traps has deterred predation in future years. 

IF at first you don't succeed  . .  .

Unfortunately this month's initial attempt by bee-eaters to nest in a disused quarry near Cromer in North Norfolk appears to have  failed - possibly because of egg- predation by stoats.

However, RSPB staff wardening the site have not given  up hope.

The birds are still present and have resumed courtship feeding, so another breeding attempt could be imminent.

But the question remains - what, if anything, to do about those stoats?
