Migration of Swallow Hirundo rustica

MRG has ringed over 70,000 Swallows, mostly as chicks or in their autumn roosts. The map presented here shows just the ringing and finding place of those birds reported from overseas, linked by a line. There is no analysis of age of the bird, season or timing of the movement, and no implication that the line is the track that the bird followed.
