Bird circling managed second journey (7)
I believe the answer is:
transit
'journey' is the definition.
(transit is a kind of journey)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for transit that I've seen before include "To pass through/across" , "carriage" , "Pass across" , "Start in for the process of being conveyed" , "Crossing - passage" .)
