As the largest member of the cat family, tigers are compellingly powerful and stealthy. It’s no wonder they’ve been one of nature’s most feared predators for roughly two million years! But in just the past 150 years, the tiger’s range has shrunk by nearly 95%.
By Nat Hab Expedition Leader Eddy Savage The aurora borealis has evoked a powerful mythological significance from different cultures for millennia. There are stories of the ancestors of Canadian Inuit playing a game of kickball in the sky with a walrus’s skull.
Bird migration may seem like a timeless natural phenomenon, but the way birds migrate is shifting dramatically, with profound implications for ecosystems and biodiversity. Here are just a few examples: Swallows and swifts are shifting arrival and departure times to align with shifting insect abundance.
Wolves have been misunderstood throughout the millennia, painted as wild and deadly beasts. They are creatures of myth and folklore—often to their detriment. The truth is that wolves are highly intelligent animals. They are extremely social and develop close bonds with family members and within their packs.

At the intersection of biology and psychology, there’s a tantalizing field of study called biomusicality, which looks at whether different species are capable of behaving in ways that show that they recognize aspects of music, including beat and rhythm. For example, female crested gibbons display jerky, almost robotic patterns of movement.
While Scotland has long been known for its culture-rich cities and castle-crowned crags, it is also one of Europe’s last great wildernesses. At almost every turn is a vista that will stop you in your tracks—so keep your camera close at hand!
