Thank Liam, I'm leaning towards Collocalia troglodytes and confirmation is requested.
Gerardo, they do emit clicking sounds within our hearing range for their echolocation. More here:http://en.wikipedia.org/wiki/Swiftlet
This one flew into one of our cavers in a tight passage & she was able to hold it just long enough to take this shot and was released unharmed immediately.
ooops, you're right, Nopayahnah, I'll delete the previous one since discussions have begun here.
Can you tell us about there echolocation to navigate in total darkness in the caves?
