Thanks BalincaguinConservancy

Thank Liam, I'm leaning towards Collocalia troglodytes and confirmation is requested.

This may help you narrow down the ID:

Gerardo, they do emit clicking sounds within our hearing range for their echolocation. More here:

Oh that's nice. I was wondering if it had been injured. Thanks!

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?

It is nice. Why did you post it twice? And why were you holding it?
