Wiwer goch, by the way, is the Welsh name for the red squirrel.
Anglesey is the stronghold for the species in Wales and especially Newborough Forest / Coedwig Niwbwrch.
The grey squirrel has been absent from the island for a few years now, which is good news for our native red.
I’m not sure if any have returned, it’s always possible across a bridge to the mainland.
I’m sure the authorities are on top of things though. The problem is the greys are bigger and push the reds out. In addition, they carry a deadly virus.
Grey squirrels are not native to our shores, it is an invasive species that originates in North America.
