About Jason Polak

Jason Polak is a bird and wildlife photographer from Ottawa, Canada. He has been interested in photography ever since he received a disposable film camera as a small child. His career as a mathematician led him to move to Australia in 2016, where he started seeing colorful parrots. A few casual shots with a lens completely unsuitable for birds got him hooked, and now wildlife photography is his biggest passion. Jason loves to show the beauty of animals to the world through photography, and one of his lifelong goals is to photograph five thousand species of birds. You can see more of Jason's work on his website or on his YouTube channel.
