The nest is the nest in our meadow, where you can clearly see two chicks. These were taken by Mark Walters.
Sadly I found one of them dead at the foot of the tree a few days ago, but the adults are still visiting so we assume the other is still alive.
Correction, when the Derringtons were here last weekend, they saw and photographed two chicks in the nest still. There must have been three to begin with.
