The 18 birds were discovered independently by three observers, one of them while riding on a train with a speed of 130 km/h. Two birds of this group were colour-ringed, of which one was read (inscription 2H1). It appeared that this bird had been ringed on 14 September 1999 at Logroño, La Rioja, Spain (Alvaro Camiña Cardenal in litt), making the sensation complete. Most seemed to be second-calendar year birds; at least three birds were two years old or older (including the bird of which the ring was read). Annual Report 2001. |
