Any brown songbird of the family Alaudidae (4)

Ross

I believe the answer is:

lark

(Other definitions for lark that I've seen before include "Small songbird or playful action" , "Jape; bird" , "Foolish activity, songbird" , "Harmless adventure" , "what one may get up to?" .)

I've seen this clue in The Independent.
