I discovered this nest today following a tip-off.
They are using a box installed for owls. Oh well - both are Birds of Prey.
The downy feathers are being rapidly lost and replaced with flight feathers. It will not be long before these will fledge.
The Kestrel lays between 2 and 6 eggs. This is a group of 6 chicks so they have done very well. I have lots more images to process and may add to this thread.
BTW I had to use ISO 1600 due to the lighting conditions.
