Vytautas Eigirdas also rings aquatic warblers himself. He uses special colorful rings that help to identify every bird from a distance – every bird carries a unique color combination.
This year the ornithologist succeeded to catch and ring 70 aquatic warblers. He also registered 20 birds having colorful rings from previous years.
