Spotted the two birds around 2:45 circling for a minute or so before they headed off to the west paralleling the 6th concession. Clear looks at both birds... nice spot so early into their migration.
Other birds of interest:
-f common yellowthroat
-ruby throated hummingbird
-red-tail and cooper's hawk
-olive-sided flycatcher
Some nice surprises on what was an otherwise quiet day.
Happy birding!
