Trying to get comfortable

A brief stop at one of the Great Crested Grebes nests after a long morning shift at work. I'd probably just missed them trading places because one of the birds was swimming away when I arrived. Fortunately, the other one was apparently not sitting comfortable enough yet and stood up again a few minutes later, revealing the presence of at least four eggs. I'm not 100% certain, but a closer inspection of the photo is making me think that there could even be five of them.

Many thanks for all the comments and stars on yesterday's blip of Rosie.
