“Ah me, these signs the truth betray; My darling was the vulture’s prey. Some demon in the bird’s disguise Roams through the wood that round us lies. On large-eyed Sítá he has fed, And rests him now with wings outspread. But my keen shafts whose flight is true, Shall pierce the ravenous monster through.”

In plain words: Rama wrongly decides that the vulture is a demon in disguise who has eaten Sita. He vows to shoot it.
