Hyenas tend to follow vultures to carcasses. Mzingo wanted in on Janja's plot for the food. There is evidence that vultures were at least on neutral terms with the Pridelanders (before Scar).

We saw the hyenas eavesdropping on the vultures' meeting because "they always know what's going on in the Pridelands". Also, Mzingo was sent to talk with Kiara on Pride Rock because, as stated by Mzingo himself, Janja isn't welcome there.

Considering they are nature's clean-up crew and disease would spread without their scavenging, it makes sense why vultures are somewhat accepted in the Pridelands.
