Golf's main difficulty with waders (9)

I believe the answer is:

flamingos

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

'waders' is the definition.
The answer and definition can be both animals as well as being plural nouns.
Maybe they are linked in a way I don't understand?

'golf's main difficulty' is the wordplay.
'difficulty' is an anagram indicator.
'golfs'+'main'='golfsmain'
'golfsmain' anagrammed gives 'FLAMINGOS'.

'with' is the link.

Can you help me to learn more?

(Another definition for flamingos that I've seen is " Large pink web-footed wading birds".)

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