About Blue Tit
The Blue Tit (Parus caeruleus) is a 10.5 to 12 cm long passerine bird in the tit family Paridae. It is a widespread and common resident breeder throughout temperate and subarctic Europe and western Asia in deciduous or mixed woodlands. It is a resident bird, most birds do not migrate.
The azure blue crown and dark blue line passing through the eye and encircling the white cheeks to the chin, give the Blue Tit a very distinctive appearance. The forehead, eyestreak, and a bar on the wing are also white. The nape, wings and tail are blue; the back is yellowish green; the under parts mostly sulphur-yellow with a dark line down the abdomen. The bill is black, the legs bluish grey, and the irides dark brown. The young are much yellower than the old birds.
This is a common and popular European garden bird, due to its perky acrobatic performances when feeding on nuts or suet. It swings beneath the holder, calling tee, tee, tee or a scolding churr.
The song period lasts almost all the year round, but is most often heard during February to June.
