International winger? (4)

I believe the answer is:

tern

I'm a little stuck... Click here to teach me more about this clue!

'winger?' is the definition.
(tern is a kind of bird)

'international' is the wordplay.
'TERN' is hidden in amongst the letters.
But, I am unsure how this is indicated.

Can you help me to learn more?

(Other definitions for tern that I've seen before include "Sea bird, a small gull" , "Small slender gull" , "Rent out this gull" , "Rent out the bird" , "Three-masted schooner" .)

I've seen this clue in the Evening Standard.
