Field Guide features one species on each page with a large, primary photo and several smaller photos showing the species in different settings and seasons. Each page features bullet points with identification facts for that species. Measuring 3 3/4" x 6", the front and back covers are coated with 10 ml plastic, and each internal page is coated with an extra-heavy layer of UV coating, making the entire book wear, water and dirt-resistant and built to take the poinding that comes from being outdoors.
