A Bird Attack!

It had remained quite windy yesterday, but today late morning it started getting better, and now at 7 pm there is no wind. I went out for a walk with NK (a colleague) and then a skua tried attacking us. Perhaps we had gone very near its nest. I had seen its shadow hovering over us, but suddenly I realized this shadow was right near my feet, small and dark. I realized immediately it was right over my head. I saw it just 1 ft away from my head with menacing eyes and open claws. Its beak is like that of eagle or kite since it is a hunter and scavenger. Its pet birds for hunting are snow petrel and young Adelie penguins. I tried to shoo it away by sound and moving my hand. But it was not to be scared. I had my camera with me and I started rotating it above my head vigorously since I did not want to be attacked on my face. I was not wearing big snow glasses. NK tried to protect himself with a screw-driver that he was carrying. It attacked the screw-driver a few times, and then flew away. By this time we had also moved away from its supposed nest.
