I'm just being honest. Anyone who tells you they know what its like to be a bat, or any other animal, and what drives it's behavior is lying.
"Animals eat when they're hungry" is fine story, and obviously there is a lot of truth to it, but there are also obviously a lot of exceptions too.
Do you really think the Grizzly, preparing to hibernate, who can barely walk because he is so fat, and is eating his 50th salmon of the day, is eating because he is hungry?
What about the baby birds, mouths open when parent returns with food? Hungry, or just instinct?
What about an alligator that can go months without eating. In captivity it will eat every day if food is offered, and get obese (so keepers don't do that). Is it eating when hungry?
What about grazing animals that eat nutritionally poor food, and spend most of their waking hours eating? An elephant eats for 12-18 hours a day. Is it always hungry, or has evolution just given it survival instincts to behave like this?
When the bat leaving it's cave at dusk to go catch insects, is it hungry? What is it like to be a bat?
Ah..That makes sense. Because nothing you were saying making any sense to me.
