Do birds use echolocation?

We know that birds have highly advanced vision. Whether it's an eagle spotting prey from a great distance, or a nightjar snatching up insects at night. No matter the conditions, they have the appropriate anatomical tools to make their living.
But there's a small subset of birds that could be considered oddities, as they roost and build their nests in caves. To find their way around in the pitch-black darkness, they use echolocation.
