Question about the american bald eagle, squirrel, bear and robin?

why are they all called american when they are found in canada to?Question about the american bald eagle, squirrel, bear and robin?
they are called american because of the origin (usually continent or country) where they were ';discovered';. but sometimes the barriers between continents/countries are virtually non-existant (like Canada and the US) while others are separated by seas or mountain ranges. when there arent formidable barriers, the species tend to migrate, which is why there are american species in canada and canadian species hereQuestion about the american bald eagle, squirrel, bear and robin?
Yes, they are all American to refer to the continent of North America. Many of these species have European counterparts - there is a European black bear, a European robin, etc. The two robins are not closely related, but British settlers were reminded of their robin when they saw our thrush, and thus the name.





The tendency to name species for where they were first collected has long been a problem. For example, Cape May warblers are very rare in New Jersey, despite being named for Cape May.
Refers to the continant, (north america) not the nation (USA), also, many animals are named from where they are first found, not the extent of their range. This is also why biologists like to use scientific names and not common names.
Same reason why we have canadian geese in america.
