Scientists monitoring at Mount Moreland - South Africa?s largest Barn Swallow Hirundo rustica roost - have captured their first overseas ringed bird from a festively snowy location. The young Barn Swallow had flown all the way from Finland ? a total of 11,000 km! ?This is an amazing Christmas gift?, said Hilary Vickers of the Lake Victoria Conservancy ? sponsors of the Mount Moreland ringing programme.
