The Technique of Elimination
• Eliminate as many species as possible. Think
about what the bird can’t be before you
consider what it can be.
• Narrow down your choices by ruling out all
birds not found in your area in the season.
• Narrow down the order of the bird using habitat
and obvious characteristics.
• Try to figure out which family the bird belongs
to using less obvious characteristics and
behaviors.
• Decide the species by noticing finer details like
field marks and songs.
