“We noticed that Bellatrix wasn’t showing typical mothering behaviors, so we decided to step in to give Tonks some supportive care,” said Denver Zoo’s lead primate keeper Becky Sturges. “We provided 24-hour care for the first week and had to teach Bellatrix how to nurse, but now she is nursing well and Tonks has gained a lot of weight. Now we’re just monitoring them to make sure things continue to go well.”

It’s unlikely that Tonks will be out and about anytime soon, though. The newborn critter will remain in her nest box for a few months before she starts exploring her new habitat — and then she’ll head high up into the treetop.

What do you think of this newborn aye-aye? Cute or not cute?
