On 4 July we controlled a German-ringed Whitethroat at Orfordness, Suffolk. The ringing information showed that this bird had been ringed earlier in the spring on the island of Helgoland, Germany and when I checked against the Online Ringing Reports I was surprised to find that this was only the second ringing movement of a Whitethroat between Germany and the UK, the other being in 1952.
Although it is hard to work out why a Whitethroat should be moving from Germany to the UK at this time of year it is interesting to note how similar the movement of the bird was to the one 63 years earlier. Both birds had been ringed off the NW German coast in late April/early May and then controlled in East Anglia in late June/early July, and the movements were 483km/WSW/54 days compared with 468km/W/59 days.

Eds - Nettlecreeper is a local name of the Whitethroat. 'Controlled' is when a ringer catches a previously ringed bird, usually that he/she hasn't put on originally.
