26 May: First mass migration
Later during 26 May well over 2,500 Brent Geese were reported on northbound migration over Norway by local observers - typing their data into the fantastic Norwegion citizen science portal Artsobservationer.
Four of the PTT birds, Jan Ove, Ebbe, Niels and Fridtjof also took off this morning and the question now is - how will the satellite tagged Brent Geese fly up to the Arctic - and where will they end?
