Wintering Roseate Terns in Funchal

In early December Madeira Wind Birds reported a couple of adult Roseate Terns in Funchal harbour which have also been seen the year before, by the same month. Then, for a while, only 1 Roseate Tern has been recorded in Madeira and now, on the 2nd of March 2008 the record is for a juvenile and an adult! Considering December 2007 and January 2008 were very warm in Madeira, more like Spring than Winter, we guess we can presume this juvenile was born already this year...
