German rogue asks how to get birds! (8)

I believe the answer is:

goshawks

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

'german rogue asks how' is the wordplay.
'german' becomes 'g' (abbreviation).
'rogue' indicates an anagram (letters go rogue).
'asks'+'how'='askshow'
'askshow' is an anagram of 'oshawks'.
'g'+'oshawks'='GOSHAWKS'

'to get' is the link.

I've seen this clue in The Independent.
