In this 2007 episode a grey squirrel is captured and will be set loose in the woods. In the UK greys are a generally reviled invasive species who are wiping out the beloved native red squirrels. In some parts of the UK it was, in 2007, illegal to release a grey squirrel into the wild; it was actually a crime to fail to report grey squirrel sightings to the authorities. By 2014 some recovery seemed to result from setting squirrel traps in the woods, killing captured greys, and releasing any reds.
