Ringing recoveries

With not much to talk about due to the horrendous conditions putting an end to any ringing activities or migration here at Gedser today, I will touch upon some recent ringing recoveries.

Back in October the Song Thrush was a common migrant in Gedser and were caught almost daily in fluctuating numbers. 161 of them have been ringed this year and 1 of which has recently been found by a member of the public. 8184222 was ringed by me on 11th October this year. We have recently heard from the Zoological Museum in Copenhagen that this individual has been found in the Netherlands some 511km away from Gedser and in just 15 days. This bird was unfortunate in that it was killed by a cat and freshly dead, so we can only guess at where this bird was heading! Below is a map of this recovery.

Another astonishing recovery received today involved a Blue Tit. What is astonishing is not the distance that the bird moved; a mere 82 km but that the ring was actually read in the field by 2 bird watchers! See map below.

Ringing really can throw up some surprises and it always worth checking out your local area be it a park, harbour or a field! Often there are ringed birds out there ready to be seen and reported. Always check any dead birds you come across for rings too; though be careful when dealing with these. Findings of ringed birds can be reported by sending an E-mail to ringing"@"snm.ku.dk or by writing to the Museum at the address below.
