Class II. LONG TAILED TITMOUSE. 539 



ternal materials are mosses and lichens, cu- 

 riously interwoven with wool ; within it is lined 

 very warmly with a thick bed of feathers ; it 

 lays from ten to seventeen eggs. The young 

 follow the parents the whole winter ; and from 

 the slimness of their bodies, and great length of 

 tail, appear, while flying, like so many darts 

 cutting the air. They are often seen passing 

 through our gardens, going progressively from 

 tree to tree, as if on their road to some other 

 place, never making any halt. 



It is seen in Italy flying about during the 

 whole winter.
