Second infant was a surprise to keepers.
The tiny cubs were born to 15-year-old mom Lun Lun on Monday night at Zoo Atlanta, the first giant panda twins to be born in the U.S. since 1987.
Lun Lun has had three other cubs, but has never had twins.
An ultrasound on June 30 showed that Lun Lun was pregnant — but it only revealed one cub. So, the animal care team was surprised when the second baby arrived, two minutes after the first.
“It’s TWINS!” the zoo announced on its Facebook page.

A crowd gathered to watch a firefighter save a dog from a second-story window ledge in Brooklyn.
A dog appeared to wiggle his way out of a second story window in Brooklyn, but because the window had a guard that’s required in apartments where children live, he couldn’t get back inside.
Firefighters backed their truck up to the building, and a rescuer in the cherry picker worked to gain the trust of the pup, who was trying to keep his footing on a 6-inch ledge. The firefighter offered the dog water and treats before putting a leash on him and carefully lifting him into the bucket.
