The beauty and fascination of birds is unrivalled. Every day of the year, immerse yourself in their world with an entry from A Bird of Day, where Dominic Couzens offers an insight into everything from the humble Robin to Emperor Penguins, who are in the midst of Arctic storms protecting their young on 1 July. Or discover the fate of the Passenger Pigeon which became extinct through overhunting on 1 September 2014. If you ever visit the Himalayan uplands, go in late November when you can see a flock of the cobalt blue Grandala birds, which is one of the wonders of the natural world.
