Three osprey sighted in the vicinity of the two nests. However, nest 13 (where incubation behavior had been noted 5 days ago) was unoccupied for the duration of the observation (approximately 7:30 am to 9:00 am). The only exception was when a small black bird (possibly a crow) landed on the nest and one of the osprey from nest 14 flew over and chased the crow away (see photos). After that two of the three osprey had some sort of confrontation over nest 14. (see photos)
