How do you think Mufasa found the hyenas after the morning report and pouncing lesson?

The mole who informed Zazu who informed Mufasa, showed the way + Mufasa must have sooner or later caught hyena scent.

yapori...i think so

Zazu told Mufasa that the hyenas were in the Pridelands and then Mufasa went after them. He could hear the zebras panicking and then found the herd.

I think Mufasa would have seen the hyenas in the pride lands
