Is there anything to confirm whether or not falcons exist in the Star Wars Universe? If they don't then what is the in-universe reason for the name of the Millennium Falcon?

Regarding canon - other than the Falcon name it appears not. It seems an unnecessary question imo - one could engage in ever increasing navel gazing over the necessity of language use in the film. Do ducks exist in canon? They are referenced in Episode 1. Does a Star Wars duck look like a duck and walk like a duck or is it different from an earth duck?
The name itself inherently implies that such a creature exists in some form and that is swift and agile. This is the simplest and logical explanation
