Hi Matthew, they were first seen there nearly a year ago (a pair) and subsequently several birds were seen opposite the road at Upper Stranger Pond where they bred. I believe the birds never left the area and have been seen on and off since about October last year at both these sites. You can see the timeline icon next to the the species name at the top of the screen once you have confirmed the record and this shows past records within the nearby vicinity.
Thank you @MatthewFrawley Yes we have been lucky enough to get them at both locations that @natureguy mentioned. Looks like you need to search on Upper Stranger Pond to see the timeline there also.
