Great tit

The great tit ("Parus major") is a passerine bird in the tit family Paridae. It is found throughout Europe, the Middle East, Central and Northern Asia, and parts of North Africa. Most great tits do not migrate except in places with harsh winters. 
The great tit has a black head and throat. The back is olive-green and the stomach is yellow. It has a white spot on its cheek. The great tit is 12.5-14.0 centimetres long and weighs 16-21 grams. It is a song bird, and has up to 40 kinds of songs and sounds.
In the summer it eats insects and spiders. The great tit eats for example cockroach and grasshopper. 
The female lays about 12 eggs and broods them by herself. Both parents take care of the baby birds. The great tit feeds its fledglings on protein-rich caterpillars.
