Towards the end of May, seven blue tits hatched inside a bird box in the Granada garden.
Sadly, we think six of them died, but this week we watched the remaining fledgling fly the nest for the first time.
Here is some speeded up footage showing the blue tits' story so far.
Fred installed a bird box with a camera on the roof garden a few months ago. It's now home to a family of tits and is producing some lovely shots.
The two remaining Granada blue tit chicks have survived the night. One of them is beginning to develop the yellow chest plumage of a juvenile bird. When they fly the nest, they will be a mix of grey and yellow, the blue colouring not developing until later.
Five of the seven blue tit chicks in the Granada bird box have died, but the two survivors are thriving.
Read the full storySadly 5 of the original 7 blue tit chicks have now died. Such a high death rate is typical of blue tit broods, but it does mean the remaining chicks have a greater chance of survival because there is more food to go around.
