CALGARY -- The Calgary Zoo's female elephants could soon have a new home.

Last year the zoo announced it was going to relocate the pachyderms because after 40 years, the zoo couldn't give the animals the space they required.

A decision will be coming within six weeks after zoo officials finish visiting sites to determine the best placement for Kamala, Swarna and Maharani.

The zoo says the elephants' long-term welfare is better served by being part of a large social group; something that can only be achieved at a facility with more year-round space.

A decision on a new home for Spike, the male elephant, will be made in conjunction with the Miami Zoo, which still owns him.

Animal-rights organizations have taken issue with the decision of the Valley Zoo in Edmonton to keep its lone female elephant, Lucy.
