Do they see pink humans?
From ANIMAL PEOPLE, Jan/Feb 1998:
BENGAL––Cops, sociologists,
and commanders of troops know that males
without females may start fighting and
boozing––and that’s the problem among the
elephants of eastern Bengal, reports the
Wildlife Institute of India.
Normal Indian elephant herds,
they say, consist of one male to several
females, governed by the eldest female.
Adult males usually travel apart from the
main herd when no females are in estrus,
but remain under herd rule. Bachelor elephants
are normally just the grown but not
yet mated, and the very old or dispossessed.
Few and alone, they historically kept out of
trouble.
