OSFN Indoor Meetings are normally held on the second Thursday of the month at 7:00 p.m. at the Bayshore Community Centre, 1900 3rd Ave E Owen Sound. There are no Indoor Meetings in July and August. Please see the individual event listings below for more details.

We invite speakers with a wide range of expertise from Grey/Bruce and other parts of the province. These evenings are open to the public. The auditorium is open by 6:30. The meeting gets under way at 7:00, and may include brief announcements by other organizations as well as OSFN club activities, club business, social time, nature sightings and reports.

The club also offers a full schedule of outdoor activities during the year. Through these outings, members learn more about the birds, plants, mammals and geology of this part of Ontario. We also keep a protective eye on our precious natural areas.
