I caught bird flipping over salad ingredient (7)
I believe the answer is:
iceberg
'salad ingredient' is the definition.
(iceberg lettuce is often used in salads)
'i caught bird flipping' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'bird' becomes 'grebe' (type of bird).
'flipping' says the letters should be written backwards.
'grebe' in reverse letter order is 'eberg'.
'i'+'c'+'eberg'='ICEBERG'
'over' is the link.
(Other definitions for iceberg that I've seen before include "Maritime danger, mostly underwater" , "Hazard in Arctic sea" , "Wrecker of Titanic" , "Main hazard" , "arctic feature" .)
