30 OUR MIGRANT BIRDS 



Language. Song, " a wild desultory warble," not 

 heard in England. Another note a harsh " chak." 



Habits. Gregarious. Shy and wary. Flight strong, 

 rapid and rather undulating. Vagrant in their move- 

 ments. When feeding the flock always moves in the 

 same direction, and not at random, and when perched 

 they always face one way. Extremely clamorous 

 just before roosting time. 



Food. Insects and worms, soft fruits in season. In 

 winter on any kind of berries, especially those of the 

 juniper and hawthorn. 



Nidification. Breeds in Northern Europe.
