Yesterday ornithologist Vytautas Eigirdas visited the most important aquatic warbler breeding site in Lithuania – Tyrai marsh in Kliošiai landscape reserve – and identified the first 4 aquatic warblers that came back from wintering grounds. One bird had special colorful rings that Vytautas Eigirdas put on its leg last year in May. The bird was noticed almost in the same place. The ornithologist says that the birds are not active – they started singing only slightly before dark. Soon more aquatic warblers will fly back to Lithuania and other breeding grounds and start a new fight of survival.
