NOVA Season 1 Episode 8 Bird Brain: The Mystery of Bird Navigation

In NOVA season 1 episode 8, titled "Bird Brain: The Mystery of Bird Navigation," viewers are taken on a fascinating journey to understand the astonishing abilities of birds when it comes to navigation. From the Arctic Tern's incredible annual migration between the North and South poles to the homing pigeon's remarkable ability to return to its coop no matter how much it is disoriented, researchers have puzzled over the mechanisms behind these feats for centuries.

To uncover the mystery of how birds navigate, the episode features leading scientists from fields including biology, psychology, physics, and engineering. They use cutting-edge technology like GPS, radar, and electromagnetic fields to piece together clues as to how these winged creatures move across thousands of miles without getting lost.

One of the most intriguing aspects of the program is the focus on the tiny but powerful hippocampus, a part of a bird's brain that is responsible for spatial memory. Viewers are taken on a unique journey to understand how the hippocampus works and what makes it so essential in allowing birds to navigate.

Additionally, the episode explains how birds use not only the earth's magnetic field but also the natural polarisation patterns of light that are unique in each hemisphere. The program explores how birds detect the Earth's magnetic field and precisely align themselves with it to stay on course.

Another interesting aspect of the episode is the way researchers have used computer simulations to model different aerial routes and track how birds follow them. The program explores how these simulations give insight into the factors that affect bird navigation, such as wind patterns or the presence of land masses.

Throughout the episode, viewers are introduced to a cast of bird species, including homing pigeons, Arctic terns, and sooty shearwaters. The program documents the incredible range of behaviours and skills that each bird uses on its journeys, including navigating by smell, sight, and sound, as well as maintaining a precise internal map of where they are at all times.

Overall, "Bird Brain: The Mystery of Bird Navigation" is a fascinating exploration of one of nature's most impressive feats. Anyone with an interest in science, birds or those who are just curious about the world around them will find this episode illuminating and engaging. With stunning visuals and a cast of experts, this program is sure to astound and leave viewers in awe of the incredible abilities of winged creatures.
