Cormorants in the Danube Delta and on the seashores of the Black Sea. Probably Great Cormorant (Phalacrocorax carbo).

The White Stork (Ciconia ciconia) - photos taken in August last year.

Common Tern (Sterna hirundo) chicks waiting for food on floating reed and water lilly leaves.

European (or Common) Magpie (Pica pica) from the crow family.

Unidentified flying bird. Seems some kind of (juvenile?) woodpecker, but I have no idea what species this could be. So if anybody knows please do leave a comment.
UPDATE: Eurasian Jay (Garrulus glandarius)
