We haven't heard yet any details from the 3 foreign controlled Siskin I reported on in my last mailing; but we caught another ringed bird 2 days ago which sheds a bit more light on the derivation of all these birds.
On the middle line of this ring you can clearly see the letters LITH; this bird was originally ringed in Lithuania, which is even further east than our previous birds.!!
A couple of us have visited the Kaliningrad region of Russia, which borders the eastern Baltic and is directly south of Lithuania. From our experiences, many thousands ( probably millions) of birds migrate along the Lithuanian and then the Kaliningrad coast before entering Poland and spreading out over Europe. Our suspicion is that at least some of the Siskin roaming around the UK at present are birds from Russia, this one of which was ringed en route in Lithuania. Time will tell, but we are quite hopeful that of the 2000+ Siskin we have ringed in the last 2 months, some of them may be controlled in eastern European countries where we think they have come from. Fingers crossed!!
