Last year this same pair laid and hatched 3 eggs, but the third egg was a few days after the first two. I will of course be checking the video form this week to see if there are any more to come.
They are being careful parents and keeping the eggs well wrapped in dry grass, though you will notice that the dad looks a bit less confident when he gingerly takes his turn to sit on the eggs for a while.
You may also spot that he brings in a fish having already eaten half, and then cheekily flies off with it having not offered any to his mate.
