Birds from another nest (5)

I believe the answer is:

ernes

'birds' is the definition.
(erne is a kind of bird)

'from another nest' is the wordplay.
'from' indicates a hidden word.
'ERNES' is hidden within 'another nest'.

(Other definitions for ernes that I've seen before include "Sea-eagles" , "Certain birds" , "They fly across the sea" , "sea eagles" , "Irish lough's" .)

I've seen this clue in The Globe and Mail.
