흰머리오목눈이 { Long-tailed Tit (A.C. caudtus )}

The long-tailed Tits (A.C.magnus) are a common resident bird around us.

However, the all-white subspecies of the head,  long-tailed Tits (A.C. caudatus) are a rare winter visitor . 

 

Some plumage variation across range; adults in northern parts of range have white head without broad black eyebrows and whiter underparts, while those further south are darker.

Juveniles (seen in summer–early autumn) have brown head sides; become like adult by winter.
