I noticed that Malenia shares the water fowl start up with another homing thrusting attack that heavily punishes you if you run away lol. It's almost the same anime pose where she floats a little bit in the air but the thrust interrupts her air stance, you're supposed to roll at the last second because she homes in. Water fowl start up lasts almost a full 3 seconds but if you misjudge and don't run far enough you're eating all of it
