Below first map: coincidence? Two juvenile logger birds of 2023 cohort both decided to travel further south, in western France. Yellow dots is SACZ, which arrived just south of island Belle-Île-en-Mer on October 9th, 2023. Blue dots is SAFW, which also arrived at its most southern location, also on October 9th. Both logger birds decided not to travel further.
