Two Great Horned Owls (Bubo virginianus) talk to each other on a mid-march night at Peck's Lake [Arizona]. They're sitting about 150 meters apart, and a third was calling about a half mile away. These owls nest in the steep rocky cliffs around the lake and hunt in the flatlands surrounding the lake and marsh. I have "compressed" this file, the actual time between calls is about 15 seconds, but the time between the query and response is accurate.
