At least this many. Group of 9 seen distantly but well perched on ridge south of lake scoped from north shore at around 5:50. Heard lots of calls from 540 till around 6. Started hearing rather close calls from ridges to the north of the lake around 7 and got great scope views of a group of 5 after seeing them fly and land at 7:25 in vegetated area below ridgetop. Very little activity detected afterwards
