Red Squirrel 
they generally appear to get along pretty well on the whole. 
They also make nests of leaves in the forks of trees, beeches in 
most instances; they cut off the leaves in branches, while they 
are still green in summer, and place them in successive layers on 
a rough platform of twigs in such a manner as to shed the 
rain perfectly, but without leaving room for more than one or 
two inmates within. 
Gray squirrels warn each other of danger with a kind of flat, 
rasping bark, finally prolonged into a whining snarl, distinctly audible 
or an eighth of a mile or more in calm weather.
