Very noisy recording Faint shriek or scream at 2.5 seconds then a series of louder shrieks from 5s to 35s all from the direction of the nest, the presumed female, bird #1. At 44.5s #2 has flown into nearby tree and giving a hoarser version of the shrieks, the presumed male. At 1:05 #1 has flown off the nest and joined #2 in the nearby tree. More shrieks of both kinds. At 1:10 bill claps start. 1:16 chittering is heard. Female calls at 1:22, 1:32.5. More calling at 1:45. all from the nearby tree, not the nest. It was probably after this that the female flew back to the nest. At 2:19 Male song and other calls from the adjacent tree. Nothing further from the nest.

As I approached the known nest tree on my way to the stakeout spot I heard female calls coming from the direction of the nest. It was dark. Sunrise at 7:04. At 6:40 AM I heard the owl on the nest (#1) give a high-pitched sort of squeaky call (heard on the recording). Another owl (#2) flew in to an adjacent tree and started returning lower pitched calls. Number one flew from the direction of the nest and joined #2. I heard bill clapping, chittering and other calls (all on the recording). When that ended, #1 flew up to the nest and #2 gave a series of hoots that sounded like male hoots. After a minute the hooting stopped and #2, the male, flew away and all remained quiet. The calls I heard are described as both defensive and in courtship. Pieplow associates chittering with copulation. This whole thing sounded like that. I also wondered if the male was bringing in prey but he did not deliver it to the nest, rather, the two met in an adjacent tree.
