How do you say hummingbird in Greek?

There isn't a single, universally accepted word for "hummingbird" in Greek. Greek didn't have hummingbirds in its native environment, so there's no established traditional name. You'd have to use a descriptive phrase, such as:

* κολίμπρι (kolimpi): This is a loanword from Spanish ("colibrí") and is the most common way to refer to a hummingbird in modern Greek.

Alternatively, you could use a more descriptive phrase, such as:

* μικρό πουλί που πετάει γρήγορα (mikro pouli pou petaei grigora): This translates to "small bird that flies quickly." This is less precise but avoids reliance on a foreign loanword.

Therefore, κολίμπρι (kolimpi) is the easiest and most understood option.
