Catch All the Red Squirrels in This Memory Match!

Since they are considered an endangered species in the U.K., a Red Squirrel Survival Trust exists to protect them, which is being celebrated today. Prince Charles, the trust's patron, lets the squirrels to roam freely on his Birkhall estate in Scotland. "They are such inquisitive and delightful characters," the prince wrote about the squirrels in an open letter applauding the trust's work. "I take enormous pleasure in having them around -- and in! -- the house when I am at home in Scotland."
