While we were in the cave a White-throated Swift flew in the entrance and disappeared in a fissure in the roof. In a moment it reappeared and flew out again. I could see no nest. Several (4) of these birds were seen flying about the entrance of the cave. This cave is about 75 feet across at its mouth and 30 feet high.

At several places in the roof were large openings (from a few inches to three feet across). These seemed to lead back into the rock surrounding the cavern. We attempted to climb up one of the larger openings but
