Unlike most birds, Goldfinches sing' as they fly, saying, 

 per-chk-o-re, per-chic-o-re. This siong When once heard can 

 not be forgotten. The wave-like motion of their flight also 

 enables one to recognize the birds when they are so far away 

 that their colors can not be seen. Their migrations are in May 

 and October. They are true friends of the farmer, for they 

 prevent the spread of troublesome weeds by eating quantities 

 of the seeds before they are scattered on the ground.
