Tree-dweller weaving thongs and belt (4,6)
I believe the answer is:
song thrush
'tree-dweller' is the definition.
I can't tell whether this definition defines the answer.
'weaving thongs and belt' is the wordplay.
'weaving' indicates an anagram (letters weaved together differently).
'and' says to put letters next to each other.
'belt' becomes 'rush' (I can't explain this - if you can you should believe this answer much more).
'thongs' with letters rearranged gives 'songth'.
'songth'+'rush'='SONG-THRUSH'
Can you help me to learn more?
(Other definitions for song thrush that I've seen before include "Turdus philomelos" , "In garden, bird" .)
