A zookeeper's efforts to earn a kangaroo's trust has paid off with a video showing twin joeys, tiny and pink, growing inside their mom's pouch.
The male Matschie's tree kangaroo twins are about 6 inches (15 centimeters) from snout to tail and they are starting to grow hair. Matschie's are an endangered species and the births at the Lincoln Children's Zoo in Nebraska are the first twins on record.
The video was taken about 16 weeks after the joeys' birth. They'll emerge from the pouch this summer.
To record the footage, zookeeper DaviAnn Buggi attached a tiny camera to her finger, then gently reached inside the pouch of the adult kangaroo, Milla.
In the wild, the kangaroos live in Papua New Guinea rainforest.
