Nest Box Diary 2009

Week 3 - 19th April

The third week started off with the third egg being laid and during the morning the female continually returned to the nest with further beaks full of animal hair, which she then carefully placed over the eggs.

Sometime around dawn each morning she laid a further egg. Afterwards, she spent some time manoeuvring the eggs and nest material, before leaving at between about 06:15 and 06:45. She returned to the nest a few times during the day, often just before midday to place more nest material over the eggs - something the Blue Tits have done previously and I'm sure is to keep the eggs cool. After 7PM, she returned to the nest, tidying it before settling down for the night.

On Friday, whenever we checked the nest, she was sitting on it, so we decided she had perhaps laid an eighth egg and had started incubating. However, Saturday morning produced another surprise, a ninth egg. So, as is often the case, she had started incubating before laying the final egg.
