Receiver station locations and antenna orientations. Start and Stop times refer to the period each receiver was active. Some changes in antenna orientation occurred (eg. CANS1 & CANS2) however sites remained active during orientation changes and therefore were unlikely to impact detections during this study. Receivers were maintained and checked for operation on a cycle of weeks or months depending on site accessibility. Evaluation of raw data showed no major receiver malfunctions except at 3 locations, all of which should not have affected data: CANS1 was non-operational for 3 days (Nov 10–13) however CANS2 was within 1 km and was operational during this time; KEJI was non-operational for 8 days (between Nov 8–19) however only one individual was detected for the first time after Nov 8th and it was first detected 150 km NE at CONRD, thus this likely did not affect overwater flight information from Sable Island to the mainland; STAGE had frequent blackouts however LOT1 was within 5 km.
