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)

Mute/White Swans (Cygnus olor) taking off from one of the lakes in the Delta of Danube.

Green Woodpecker (Picus viridis) high up in the tree at dusk - helpful lighting given by my Metz flash.

Little Egret (Egretta garzetta) in the Delta Of Danube Biosphere Reserve.

Female Common/Eurasian Blackbird (Turdus merula), or at least this is my best guess. It is very similar to the Fieldfare (Turdus pilaris).

Head and neck of a Black Swan (Cygnus atratus) and Mute Swan (Cygnus olor).

White Wagtail (Motacilla alba) - most probably from the subspecies Motacilla alba alba.

Female Mallard wild duck (Anas platyrhynchos - "flat-billed duck").
