'beastly birkenhead bar owner maybe' is the definition.
I can't judge whether this definition defines the answer.

'birkenhead bar owner maybe' is the wordplay.
'birkenhead' becomes 'b' (head letter of 'birken').
'maybe' is an anagram indicator.
'bar'+'owner'='barowner'
'barowner' with letters rearranged gives 'rownbear'.
'b'+'rownbear'='BROWN BEAR'
