The Dobrogea region in south-east Romania includes ancient steppe country and the magnificent Danube Delta wetlands.
Every winter tens of thousands of visiting geese are attracted to the enormous prairie fields of new wheat. A short flight away, hundreds of lakes provide a safe resting place for them.
In summer these same delta waters - a maze of channels, islands and marsh wilderness - become a wildlife paradise, where the great reedbeds provide a secret breeding retreat for the spectacular white pelicans - their last stronghold in Europe.
