Hi
To start with I have a nest box with a camera inside. Late March a Bluetit started to inspect the box. Beginning of April she was very industrious pecking at the floor and sides taking pieces of wood off from everywere. Large pieces where taken out and others left in the box.

She then began to build a nest, I thought Ok will see the eggs as they are laid, but I was going away on holiday. Thoughts of coming back to a batch of eggs after 2 weeks away. On returning home on the Sunday no eggs. First thing Monday morning and first egg laid and 1 each day for 8 days, last egg on Monday 27th April, she has been sitting on them ever since. Now waiting for the first chick to hatch.
