This post continues the discussion of the Seven methods of identifying birds.
Color and pattern:
This is the basis of the "Peterson System" of bird identification. The Peterson System illustrates birds all in the same pose, with patternistic drawings. Arrows then point to the unique area of color or pattern on a bird that separate it from similar species. Wing bars, eye rings, eyebrow stripes, tail spots, and all such feather groupings are used in a stylized way to aid identification. Ingenious.
Newer birders start here. Sadly, many never advance because they don't learn the remaining methods of identifying birds. And it doesn't help that some "field guides" are arranged by color, effectively preventing bird watchers from advancing further.
