Tue Siskin (or Aberdevine, as it is also called with us) is found generally throughout Europe, 
breeding in Northern and in the northern portions of Central Kurope, visiting the southern 
countries during winter, at which season it is also met with in North Africa. It inhabits Asia 
as far east as China and Japan, but is not found in America. With us in Great Britain it is a 
resident, breeding in the northern portions of our island and occasionally, though rarely, in the 
central and southern districts, which latter it usually visits during winter, at which season it 
appears to be generally distributed throughout the southern counties. Mr. Mansel-Pleydell 
states that it visits Dorsetshire periodically in autumn and leaves again for the north in spring. 
It is frequently met with in Kent, Surrey, and Middlesex in the spring and autumn; and 
Mr. Stevenson says that it visits Norfolk regularly towards the end of the autumn, and again late 
in January, but its numbers vary considerably in different seasons. Mr. Metcalfe informs me
