The female, who I do think is Princess, has been working daily on the scrape in the nestbox and it is a nice size now - something that Smiley hasn't been able to accomplish on his own this year or last. This might be an excellent indication that she is seriously considering the nestbox this year. However (and you knew there would be one) someone visited the nestledge for the first time that I have been able to observe this season ... just one bird and it didn't stay more than a couple of minutes. The pair have been copulating quite energetically over the last week, so we are perhaps going to have eggs a bit earlier than usual here, but it isn't up to me, so we will just have to see ...
