Now Fay has laid her first egg! Bluetits' eggs are clearly much smaller than those laid by a great tit!
And Greta now has three!
Come on Abby - how about an egg from you? That would make our nest box collection complete!
At least Angus is doing his bit - here he prepares to feed Abby on the nest.
Angus passes the food to Abby - a bluetit kiss?
Abby has brought in a huge amount of nesting material. She is almost buried in the stuff!
Gustaf is doing his bit too. This is a late evening snack for Greta.
Gustaf passes over the food to Greta.
Nine minutes later Gustaf is back again with more food.
At nearly a quarter to eight, Greta settles down for the night.
