Rabbit (Oryctolagus cuniculus)
That all changed in 1955 when Myxomatosis was introduced. It seems that the Rabbit was becoming to be seen as a pest (probably linked to the shortage of food supplies during the war?) and man decided to take control. This vile disease decimated the Rabbit population and it ceased to be part of the human diet and other predators of the Rabbit declined rapidly, especially the Buzzard.
In recent years the numbers have begun to rebuild but it seems Myxomatosis is still around and when numbers in a given area grow so the disease reappears and knocks them back again.
No longer favoured by we British as a meal it remains popular with foxes. stoats, buzzards and other animals at the top of the food chain and the Rabbits revival has certainly been matched by an increase in Buzzards over the last thirty years.
