Saturday night raining steadily at Nicasio; absolute quiet other than the rain, no owls. Then at 3:48am it starts! I hear the great horned owls again. To me it sure sounds awfully close. A running conversation is ongoing from 3:48 until 4:09am (at that time it seemed they moved on, I only heard the one in the distance). Salt landed on his favorite spot at 4:53am and stayed until 4:58am. He seemed fairly relaxed, so I gather the gho's did move on. Salt again showed up for a minute at 5:50am.
I recorded a long video (and that's not the whole time) of the great horned's in hopes of anyone who knows more about the communication between them could possibly enlighten us. I know if they took over the area that the barn owls most likely won't stay. Are they as close as it sounds, you think? The long video is just the sounds of the GHO's. The other video is of the two times Salt showed up. Still no sighting of Pepper! She was seen only briefly Thursday night in the box. Here's hoping to back to normal tonight ♥
I have found what the sounds they are making means. It is a "Territorial Hooting Duet".
Since I haven't figured out how to embed a player here yet (oy), here is the link.

Notes from the author:
NOTES: Territorial hooting by pair. Pair was duetting nightly in this area. A neighboring pair was also singing. A sequence presumed to be copulation by the pair is heard. Different vocalizations including prolonged hooting and a chitter call by the female are heard during the presumed copulation.
