He mounted her for a few seconds - she was entirely passive, her head arched far back - and then hopped off and flew away. As I moved on, I heard two tattoos from that direction.

At 9:38 r. came up, hitched up and down, looked in and went in. 9:40 - n. arrived at nest, squawked, moved aside, preened and scratched. r. then squeezed out, flew off with a rattle, n. went in. N. looked out a few times, came out at 10:00, diving down and alighting crosswise,
