BTO East Glamorgan/Dwyrain Morgannwgさんのイラストまとめ

The reptilian leg of a Mute Swan with ring W28940 seen at Roath Park Lake, Cardiff last week. Thanks to @_BTO we know that it was ringed 10km away at Cosmeston Lakes, nr Penarth, in its second year in Jan 2011, so it's nearly 10 years old. Every #ringing recovery tells a tale.
