While it’s great that nature photography is so popular, this brings with it one big challenge – everybody is doing it. This means you need to figure out how you can be different (assuming you want your photos to be noticed).
This could be anything from focusing, and specializing on a single family or species of animal, to developing an artistic quirk and style in your photography. Personally, I spend a lot of my time photographing red squirrels – thousands of hours actually, to give you some idea. All this time has allowed me to learn about the animal, and capture behaviour that others have not managed.
