Wandering with tot, hear a songbird (11)
I believe the answer is:
whitethroat
'a songbird' is the definition.
(I've seen this before)
'wandering with tot hear' is the wordplay.
'wandering' is an anagram indicator.
'with'+'tot'+'hear'='withtothear'
'withtothear' is an anagram of 'WHITETHROAT'.
(Other definitions for whitethroat that I've seen before include "Warbler nesting in May 'like all the 1 downs'" , "Songbird" , "Variety of warbler" .)
