A Rock Wren was photographed and posted to the Facebook Group "Bird Identification Group - People Helping Others ID Birds" late last night from the town of Glen Robertson which is northeast of Cornwall, almost at the Quebec border. Apparently the bird has been present for "a while". All of the information at this point is in the Facebook post and associated comments: https://www.facebook.com/groups/bird.identification/permalink/1685285691641126/ Good birding, Mike Burrell
