This was a mother falcon protecting her young against a much larger pelican who came too close to the nest. The moves were so violently fast as this pelican did everything to run for his life. But the falcon, the fastest wildlife on earth, managed to make a grab on the pelican! It was a split second quick and they then separated. When I look at my shot, oh wow! she did a head massage on the pelican! During breeding season, this female falcon can get very protective of her young. Anything comes close to her nest may get a fierce attack and some get killed.
