Monkey still traumatized after sister's abduction
Monkey thieves stole April on April 22, 2008, but apparently had a change of heart two days later. They left April in a small storage box behind a building in Saint John and an anonymous call led police to her.
April was returned to her family at the zoo and the story was thought to have had a happy ending.
But since then, April's older brother, Charlie, seems to have been deeply affected by the ordeal.
Charlie became overly protective of April after she was returned to the zoo.
And now, when any new baby monkey is born in the zoo, Charlie tries to keep them out of harm's way, as well.
The monkey holds onto them but the unintended consequence is that Charlie is not letting the babies get enough nourishment from the mother.
Charlie's overprotective tendencies have resulted in three baby monkeys dying since April was stolen.
Charlie, April to be moved
"He's not taking them through aggression or not wanting babies there," Collrin said.
"He's taking them as a protector. And that's something that we have to break that cycle."
Collrin said the Cherry Brook Zoo hopes a new baby will be born, and survive, after the move takes place.
She said Charlie's reaction to the ordeal is a fascinating and unfortunate development of an otherwise happy story.
"We thought everything was OK," Collrin said.
"Time [has] shown us how fragile these animals are, and how easy it is to completely make a group dysfunctional."
