Black-headed Gull TLW5

I noted the darvic type ring on this 1st winter Black-headed Gull at Bakewell on 25th September, traced the ring to Poland and sent of the details.

Turns out it was ringed near Krakow on the 21st May, so it has travelled 1535km in 127 days. We often assume that birds we see regularly are locally bred but that's clearly not the case as we'll see soon with Blackbirds and Robins arriving from the Continent with our winter thrushes.
