The morning began with a very wet hawk sitting on the nest. With the rain darkening their feathers and the camera angle, it was difficult to tell whether it was the formel or the tiercel, but we think it was the tiercel (male).
A little later, the formel was on the nest, along with the remains of breakfast lying on the front nest rim.
Then around noon came the news that an egg had been sighted. Here is the formel covering her egg at 12:20 PM.
The tiercel returned to the nest, and then the moment we had been waiting for - the egg!
