[[File:Eagle.jpg|right|thumbnail|250px|The [[bald eagle]] has been the national bird of the United States since 1782.<ref>[https://www.va.gov/opa/publications/celebrate/eagle.pdf The American Bald Eagle]</ref>

Bald eagles, like other eagles worldwide, are seen as symbols of strength, courage, and freedom. And, unlike other eagles, the bald eagle is indigenous only to North America.<ref>[https://www.va.gov/opa/publications/celebrate/eagle.pdf The American Bald Eagle]</ref> ]]
The conventional [[Linnaean taxonomy]] places birds in the Class Aves within the Subphylum [[Vertebrate|Vertebrata]]. [[Reptilia]], the conventional Class of reptiles, includes [[crocodile]]s and relatives, [[lizard]]s and [[snake]]s, [[turtle]]s, and the [[tuatara]]. However, birds and other, extinct [[dinosaur]]s should be grouped as archosaurs, along with the extant crocodiles and the extinct [[pterosaur]]s. Hence the conventional classification does not reflect the current state of evolutionary biology.
