That depends on whether the system found in birds is an adaptation to flight

passing solids, and being able to squirt it out at speed no doubt helps
prevent feathers being fowled.

Flying foxes aren't quite so lucky - they sometimes urinate all over
themselves while hanging upside-down.

Not only over themselves. A piece of advice based on personal experience: never pitch a tent under a tree frequented by flying foxes.
