Arctic Terns threatened by mink (3 Viewers)

That's good news then...

still can't help thinking that predator proof fences..that would also keep people out are worth considering.. might be easier to have mink/hedgehog free critical areas than whole islands/countries! Might work out cheaper too!

On a small scale, electric fencing can prove effective in detering predators (though not, unfortunately, people), but it would be impractical on many small islets as it would also deter seals and otters (though, in the latter case, that may not be a bad thing I suppose, otters being equally adept at eating birds eggs as mink!) and any birds such as Eiders that swam, rather than flew, to their nests. Several years ago in Argyll a scheme was much publicised in the local papers, encouraging anyone with a stream runnning through their property to purchase a cheap catch-alive mink trap from the local council - mink usually travel along streams and rivers. I think it would have worked too if everyone had taken part but, unfortunately, some landowners don't care too much about schemes such as this that help wildlife as a whole. Strangely though, it is usually such landowners that call for the erradication of all foxes in the distcrict the moment one of their lambs goes missing. It's all about pounds and shillings to some folk . . .
