Peek-a-bear! These sweet photos of adorable bear cubs playing peek-a-boo will melt your heart.
The tiny cubs leap out at each other from behind a tree, making funny faces and attempting to make the other one jump.
The mischievous youngsters are double trouble, making hilarious faces as they frolic in the park together.
Before settling down for a cuddle with mum, the young bears soon tire themselves out.
The adorable snaps, shot by photographer Max Waugh from Seattle, were taken at Yellowstone National Park in Wyoming.
“This has been a particularly successful year for black bear cubs in the park,” says Max, 39.
“The bears were a really energetic and fun pair of adorable cubs, and they were pretty well-behaved as well!”
The mother’s “access” was fantastic – she appeared to be very patient with lookers and gatherings that sometimes occur in the park.
“This mother was laid-back and ready to let the visitors have a good look at her adorable youngster.”
Bears are a popular attraction – it was an amazing experience to watch them.”
