Long Sault - Also identified by call. This bird was 50 yards from the Willow but true to its name the Willow was in a nice stand of willows along a creek. But even that is not a reliable way to confirm what you are looking at.
Ottawa - Identified by call, after 15 minutes of waiting. Habitat is not a clear indicator of what the species is so you really need them to call to be sure.
Ottawa - I returned to the site I had a bird recently and wanted to capture it on a sunny day. After a while it landed on a nearby perch and sang for me.
