opmerkingen 27 September-10 October, fourth calendar-year, photographed, videoed (T Janssen et al; Janssen & Bakker 2017; Dutch Birding 39: 393, plate 549, 429, plate 614-615, 2017). This bird was one of the highlights of the year, with a legendary story. It was first seen at a migration site in the province of Noord-Brabant, where it was twitchable (in flight) for the fastest twitchers only. Unexpectedly, it was relocated in the north-west of the province of Overijssel six days later (a distance of 105 km). Despite the fact that it constantly moved over large areas (also crossing the Flevoland province border), and often disappeared out of sight, modern-day communication allowed most birders to (eventually) connect with it, mainly on 4, 9 and 10 October. This plumage is the hardest to separate from Spanish Imperial Eagle A adalberti, and the identification would have faced serious problems had it not been wearing a metal ring. Although the inscription was not fully read, the ring could be retraced to Hungary. The perhaps only likely candidate, A506, had been ringed as a nestling in 2014 and was – for some reason – nicknamed Ladybug. In the aftermath, an analysis by a former committee member revealed that this was the same individual that was seen in Italy in February 2017, where it was reported as a Spanish Imperial! And, to make the story complete, probably the same bird was reported in Denmark in February 2018. Annual Report 2017.
