Hi Brian,

The first Red-rumped Swallow was described by Linnaeus in 1771 from eastern Siberia or northern China. When others collected further Red-rumped Swallows from other regions that were somewhat different in plumage they were named, and later included within the Red-rumped Swallow species in what we now call Cecropis daurica. As Linnaeus named his bird first (in 1771), daurica becomes the nominate race Cecropis d. daurica. The other races were named later, the local race emini, for instance, was described by Reichenow in 1892 and the European, North African and western Asian race rufula was described in 1835 by Temminck.

Hope this helps.

Graeme

Thanks Clive I found it after I had posted it. But why is the nominate
in China and not first described in Europe?
Best for now
