The simplest kind of guide is an ID card. Usually a folded, waterproof sheet, it's the lightweight option. The downside is that its content is also lightweight, listing only a few of the most common species. They're inexpensive and usually available in park visitor centers. These cards are a great way to introduce children to common birds they might find in the park. For beginners, a bird book arranged by color of bird may be the easiest way to get started. However, these types of books typically only list common species. You may find your interpretation of a bird's color differs from the book's editor!
