What do forest creatures do when they think no one is looking?
Konsta Punkka, a 22-year-old photographer from Helsinki, Finland, has been trying to find out for the last five years.
"I love to explore and show the secret life of animals," Punkka told Upworthy in an email.
Punkka, who documents his travels on his Instagram feed, explained that he uses his camera to capture the "emotions and feelings" of his often misunderstood subjects.
His many years of exploring the wilderness, tolerance for cold weather, and learned patience allow him to capture the creatures in their most candid moments, resulting in wildly expressive photos.
"A lot of people have no idea what the animals are and what they do," Punkka said. "So a big part of my work is to spread the word as well."
