The days are getting warmer, brighter, and longer, and that means summer is on its way!

We’ve already fired up the barbecue and started planning our summer holidays, but what we really can’t wait for is to spend more time enjoying the great outdoors.

Since June is Great Outdoors Month, we’ve pulled together the Firefly Great Outdoors Instagram Challenge to inspire you to get outside and enjoy the wonders of nature.

The challenge is simple: we want you to post one photo each day for the whole month of June, each one inspired by the great outdoors.

“The world would be a better place if everyone was a birdwatcher.”

Birds are fascinating animals. Descended from dinosaurs, they have evolved over 150 million years into the approximately 10,000 unique species that exist today.

Each spring around 200 species of land birds — around five billion birds in total — travel north toward their breeding grounds. These migratory birds play a crucial part in the ecosystems they travel between, and yet aside from appreciating the majesty of a flock of geese passing over or the hypnotizing beauty of a hummingbird hovering next to a flower, we often take the important presence of birds for granted.

Today, on World Migratory Bird Day, we want to celebrate the animals whose songs bring universal joy and that play a vital part in nature.

Using information from some of our best bird books, we've created a fun infographic showing some of the most impressive migration patterns of birds around the world.
