Excitement when going round road to find birds of prey (8)
I believe the answer is:
buzzards
'birds of prey' is the definition.
(I've seen this before)
'excitement when going round road' is the wordplay.
'excitement' becomes 'buzz' (buzz can mean excitement or anticipation).
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'going round' means one lot of letters goes inside another (some letters go around others).
'road' becomes 'rd' (abbreviation).
'as' placed around 'rd' is 'ards'.
'buzz'+'ards'='BUZZARDS'
'to find' acts as a link.
(Other definitions for buzzards that I've seen before include "North American vultures" , "Large hawklike birds of prey" , "New World vultures" .)
