So in this case to 'study' how a fox travels a GPS was fitted and the vixen was sent on its way. It revealed what anyone who knows anything about foxes would know; if not tied down by cubs foxes can travel great distances -it is even mentioned in the old fox hunting books.
WILDLIFE experts were left foxed after a voyaging vixen covered 25km of the New Forest during one night, and also took a hair-raising stroll along a busy motorway.
The female fox’s adventures were monitored through GPS tracking by the Fordingbridge-based Game & Wildlife Conservation Trust (GWCT).
She was fitted with the collar by the conservation charity’s predator ecologist, Mike Short, at a site near the town in April last year as part of its LIFE Waders for Real project’s research into fox behaviour.
As foxes are usually territorial, this one, which was still wearing her thick winter coat, was chosen as she was believed to be one of a family occupying the river meadows where she was found.
But this assumption was soon dispelled when the tracker showed that overnight the vixen had left the river meadows and headed east.
Moving along the course of a stream and navigating forestry tracks, she travelled about 25km across the district before settling near Totton and venturing into the town centre a few days later.
On another occasion she was tracked doing some risky foraging along the hard shoulder of the M27.
Further adventures followed about a week later when the fox headed south-west, leaving Ower, near Totton, around 10pm and travelling about 20km back across the New Forest to the Avon Valley. She followed the A31 for part of this journey.
By 5am she arrived at the edge of a country estate just south of Ringwood – an important breeding ground for threatened species of wading birds including lapwing and redshank.
The estate culls predators during the nesting season to protect the birds, but the fox managed to avoid being spotted by 20 cameras used by the GWCT’s monitoring team for over a week.
However, her luck ran out when she was finally caught by a camera set up by the game keeper and culled 10 days after returning to the Avon Valley.
The adventurous vixen’s legacy has been to provide the GWCT scientists a unique insight to help wildlife managers better understand fox behaviour, range and patterns of movement on wading bird breeding grounds.
This will help protect the nests and chicks of threatened species like the lapwing and redshank.
Mr Short said: “Our GPS-tracking of foxes in the Avon Valley has shown that while most foxes living around river meadows are highly territorial, some are surprisingly mobile.
“We don’t know where our vixen came from, but she showed how easily a fox can travel 20km in one night. This could indicate that some of the foxes that threaten the Avon Valley’s wading bird may migrate from Southampton or Bournemouth and Poole.”
