The zoo will begin selecting names, based on the calf's personality, to be translated into Thai.
A public 'name the baby' competition will likely be held, Mr Durham said.
The calf's birth on Sunday has lifted the spirits of the herd after the death of 11-month-old calf Sanook last Tuesday.
Even grieving mother Num-Oi is helping feed the new arrival, unusual for elephants in captivity.
"When a new calf is born, it's not uncommon for that calf to feed off a related adult female," Mr Durham said.
"In captivity, it is a little more unusual because the elephants aren't related."
The calf can be seen by zoo visitors from Wednesday.
