Thank you for your response, I did check ebird for any possible sightings of course there were none since late August. I did not look at Cave Swallow data.
About an hour after the first sighting my wife and I watched two Swallows zip across the sky heading in a Southerly direction along the edge of Georgian bay
Napper:)
We are ten minutes North of Tiny Marsh by vehicle and lets say 500 feet (est) from Georgian bay.
