Nice pics, folks.
The large white bird in the marsh in Sergey's pics is called a Casmerodius albus. Aka: Snowy Egret.
The smaller gray bird on the beach looks like a Larus heermanni. AKA: Heermann's Gull. The coloring is slightly different from the typical specimen, but that can vary due to age or season.
Just a wild guess though...might be a duck or crow
