'youth' is the definition.
(thesaurus)

'called robin?' is the wordplay.
'called' becomes 'boy' (I can't justify this - if you can you should give a lot more credence to this answer).
'robin?' becomes 'hood' (I've seen this before).
'boy'+'hood'='BOYHOOD'

Can you help me to learn more?

(Other definitions for boyhood that I've seen before include "State of youth" , "A man's youth" .)

I've seen this clue in the Sydney Morning Herald.
