BLUE TIT : Cyanistes caeruleus
This is one of our most common birds and is a frequent visitor to feeders.
Breeding starts from mid-April. They nest in holes or cavities, usually in a tree or wall, but also in banks and nest boxes. A nest is a cup of moss, leaves, hair and grass which is lined with down, feathers and hair. The female builds the nest and lay seven to twelve (sometimes five to sixteen) eggs. They are a smooth glossy white with a variable amount of purple-red or reddish-brown speckles. The female alone will incubate the eggs for twelve to sixteen days. Both tend the young who remain in the nest for fifteen to twenty-three days. [Arkwildlife].
This one is eating from a fatball with seeds. Their normal diet is insects, caterpillars, seeds and nuts.
