Today for #WildlifeWednesday we bring you a grey squirrel from Exeter in the UK.
Grey squirrels are famously an invasive species, pushing out the smaller native red squirrels. However, they are thought to be doing worse in some areas now due to a resurgence in pine marten populations: these predators will eat greys in preference to reds, because the larger, heavy grey squirrel has more food on it and is easier to catch.

When writing fiction and creating new settings, we often don't think about how these smaller elements and ways in which ecosystem elements balance against one another. Is there more we could do with that?
