Great tits

Parus Major ;Great tit

The largest UK tit - green and yellow with a striking glossy black head with white cheeks and a distinctive two-syllable song. It is a woodland bird which has readily adapted to man-made habitats to become a familiar garden visitor. It can be quite aggressive at a birdtable, fighting off smaller tits. In winter it joins with blue tits and others to form roaming flocks which scour gardens and countryside for food.
 in the UK we have seven varieties of tits starting with the most common , blue.great,coal,long-tailed, marsh,bearded and crested ,the latter two  I have not seen as yet.
