This is a unique situation that I could watch. This happen in Spain, it was 11 am and returning to my vehicle, I saw the bird, which was easily approached. Not at all shy, it went to and fro at about 2 m from me, as if it had not seen me, and then suddenly, it was flattened to the ground as you can see for tens of seconds, and then rebounded to eat. She did this several times and one time, as if suddenly she had seen me as I was right in front of her, she flew away. I remained deeply moved and I do so even when I see the picture. I also had time to shoot a movie, and you'll see, it's amazing. Many told me that it was for sunbathing, others a bath with ants, it only really knows. I hope that you have understood a little, because I use a translator (google).
