Some of the early paintings remind me of Escher, especially he had one with birds. However on seeing those painting in context to all the others I can see, as you have suggested, that this specific kind of bird seems to be the artist's motif. And they are able to do interesting thing with it. I did like the bird flying in winter too. However I have to agree with you that the Black Sea painting is gorgeous. It looks wonderful even through the photo, so I can but imagine how it must have looked up in real life. Thank you once again for taking us on these exhibitions.
