I'm a little stuck... Click here to teach me more about this clue!

'scratch a living' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'bird also to join seedy club' is the wordplay.
'bird' becomes 'duck' (duck is a kind of bird).
'also' becomes 'and' (both can mean in addition).
'to join' is a charade indicator (letters next to each other).
'seedy club' becomes 'dive'.
'duck'+'and'+'dive'='DUCK AND DIVE'

'to' is the link.

Can you help me to learn more?

(Another definition for duck and dive that I've seen is " Use one's wits to get something".)
