The bird box is in the Granada roof garden. We will be keeping you updated with the blue tit family's progress over the next few weeks.
There is some squabbling before they all fall asleep. Their mother is feeding them every couple of minutes. Sadly, it is unlikely that all 7 will survive to fly the nest. The size difference between the larger and smaller ones is likely to increase as the latter lose out in the battle for food.
The mother sits on the 7 chicks before flying off in search of food.
New footage from early this morning of one of the chicks snuggling up to its mother.
