I said yesterday that I was 99% certain that egg laying had begun but didn't feel that it was safe to check. Behaviour had been so different than on any of my previous visits in the last 6 weeks.  I have witnessed site selection and nest building and if all progressed  then eggs were due any day now. I couldn't visit the site until this evening and when I arrived there was no sign whatsoever of either bird, even though I watched for 30 minutes or so. I decided to check the nest for eggs and am glad to report that it contained two.  Knowing that eggs are laid in the morning on consecutive days I am pretty sure that I was correct in yesterdays assessment. To me there is nothing more beautiful than a bird's egg, it is the epitome of everything that is special in nature.  Knowing that a bird will only lay an egg when conditions are considered perfect makes it special to be able to  share in the intimate parts of it's life.  The last 5 weeks have been building to this moment and I am thrilled that she has started to lay her clutch, as hoped for.  There is still a long way to go but things are progressing just as I hoped.
