When I did my DSC 1 - some years back now - I was told that old time foresters used to have all sorts of colourful names for fallow bucks according to their level of development: brocket, pricket and so on.
I think it depends on what part of the world you come from ( I think)
This is what I was told;
BUCK - The male fallow deer.
PRICKET or SPIKER - A buck in its second year.
SORREL - A buck in its third year.
SOARor SORE - A buck in its fourth year.
BARE BUCK - A buck in it's fifth year
DOE - A female fallow deer.
TEG - A doe in its second year.
FAWN - A young (first year) fallow deer.
WEANER - A slightly older fawn.
