STOAT

I spotted a stoat on the shore in front of our house.  Extra is him going to hide under a rock.

There is a campaign to eradicate stoats from Orkney.

Danger for Orkney

Stoats are skilled hunters, need to eat a lot, and are capable of breeding very quickly. Because they are not native to Orkney there's no natural predators on the islands, and the abundance of year-round food in the form of Orkney voles means that their population can boom and then remain high.

This means they pose a significant and immediate threat to wildlife like the Orkney vole, hen harriers, curlews and Arctic terns, as well as businesses that thrive because of our incredible natural heritage.
