The blue tit nest is building up quite nicely. It has now been a week and the blue tit has been in and out quite regularly. It is usually the male who finds a suitable nesting site and then builds the nest.
He has been bringing in what looks like conifer and straw like material, wriggling around in the nest, moving nesting material around and taking certain nesting material out.
One day he bought in a piece of conifer which had some type of insect on it. It looked like a beetle running around the nest box. He quickly caught it and carried it out.
