Bird finally chooses this moment to cry out (5,3)

I believe the answer is:

snowy owl

'bird' is the definition.
(type of owl)

'finally chooses this moment to cry out' is the wordplay.
'finally' says to take the final letters.
'this moment' becomes 'now' (the present moment).
'to cry out' becomes 'yowl' (to yowl is to wail or cry).
The final letter of 'chooses' is 's'.
's'+'now'+'yowl'='SNOWY OWL'

(Another definition for snowy owl that I've seen is " Large Arctic bird".)

I've seen this clue in The Times.
