Difficult this shot ? No, not at all, you simply look out for one, follow his flight, watching till he sits down.
Then you make it yourself very easy, lie down with your camera, focus on the spot where he was sitting and wait ... very soon he comes back on the same spot again and again and you simply have to click till you got him as you want. Sudden noise chase him away but no worry , he comes back to finish a full photo session shaking his head like he was saying ' Come on man, I haven't got all day for you, still have to play around with my mates and chasing females'.
