Bird Facts

From back yard birding to long distance birding, Americans continue to pass down their interest in wild birds from generation to generation.
Some people may have a limited acquaintance with wild birds, knowing less than a handful of species, or the species that visit their yard. Specialists might be able to identify birds by the thousands of species.
Even if it's only a mascot for a sports team, almost everyone can count at least one bird identification success.
For all wild bird identification enthusiasts, here are some additional bird facts.
