Paul Parker describes himself as a conservationist. But Mr Parker conserves by killing.
His chosen prey is the North American Grey Squirrel.
His Northumbria-based organisation, the Red Squirrel Protection Partnership, say they have culled more than 15,000 squirrels in little over a year. That works out as approximately 200 squirrels a week.
"They are carrying squirrel pox which kills the reds. They also hammer the bird population, they kill the chicks to get into nest boxes and they eat eggs.
"We are going to end up losing all our reds within 10 years if we don't take these out of the equation."
A game shop in Corbridge is our next stop.
The last two grey squirrel loins are on sale in the window. The furry creatures have become the latest game delicacy.
"We sell quite a lot on the market and to local restaurants. The shop manages to sell quite a bit."
