I saw, as well as heard, two Sacred Kingfishers flying east and west along the northern aspect of Red Hill. They were moving between the same trees for the most part. It was the first time I had seen a pair on Red Hill. I kept thinking I had lost them, as they always seemed to fly further away just as I had taken a few shots. Eventually, I noticed them perched beside a hole in a branch. One bird would fly to the hole, put half its body in, before flying away. I did not want to go closer to the hole to confirm what was in there although I believe it may have been for nesting. First one bird flew away, then the other but they did not go far. I had to leave before I saw if they returned.
