I read somewhere that the grey squirrel outbreeds the red squirrel...it seems that red squirrels breed less often when their habitat is under pressure.

Add to that the squirrel pox.....which kills off the red squirrels more easily.
(In and around Formby they have a red squirrel alert system run by volunteers.
The bodies of sick or dead squirrels are removed quickly to prevent other squirrels getting the virus).
