In Charlton manor we have a Coal Tit nesting with 10 eggs.

Coal Tits will nest in hollows in trees or in mouse holes. The nest is similar to that of the Blue Tit (i.e. made from moss, wool, dead leaves and spiders' webs) except that it is moss-lined.

The Coal Tit's small (15 mm by 12 mm) eggs are smooth and glossy, and white with reddish-brown speckles. The female incubates the eggs by herself. After the young hatch, they are fed by both parents.

Breeding Starts mid April and normally will have between 7 and 12 eggs (we have 10).  The Eggs are incubated for 14 – 16 days and allow between 16 and 19 days for the fledglings to leave the nest.

In Child’s Hill School in Barnet we have a Great Tit with 5 eggs.

Great Tits will nest in a hole in a tree or wall, or among the twigs of old nests. The nest is a cup made from moss, grass and down, and lined with hair, plant down and feathers. Nest boxes are frequently used.

The Great Tit's eggs are the largest of the British tits at 18 mm by 14 mm; they are smooth and glossy, and white with purplish-red spots. The female incubates the eggs by herself. After the young hatch, they are fed by both parents.

Breeding Starts in March and normally will have between 7 and 15 eggs (we don’t have any yet).  The Eggs are incubated for 13 - 14 days and allow between 22 days for the fledglings to leave the nest.
