Nice photo and great trick to realize it!
I once had my dog Mia to help while taking photos of flamingos. They were standing in a pond, looking at me. It was to static. I let Mia sit and approached another 100m. Still skeptical, they looked at me, but did not move. Getting the camera with the tele ready, I called Mia. When she started running towards me, the flamingos began to run and take of an me: clickclickclickclickclick...... 😉
Have a nice day, my friend!
