Caught with ducks that sound like doves? (3)

I believe the answer is:
coo
'sound like doves?' is the definition.
'coo' can be an answer for 'sound' (I've seen this before). I also know that 'doves' relates to this answer.
'caught with ducks' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'with' means one lot of letters go next to another.
'ducks' becomes 'OO' (OO resembles two zeroes or 'ducks' in cricket).
'c'+'oo'='COO'
'that' is the link.
Can you help me to learn more?
(Other definitions for coo that I've seen before include "Bill and I go together" , "Dove's call" , "Expression of surprise (by a dove?)" , "Dove's noise" , "Cry of doves - cry of surprise?" .)
