bird has been tried with good success; and, after a 
few years, they would doubtless give up all desire 
to return to their wildness..

the first frosts are a signal to them to escape to 
warmer regions. They are found on our larger

there is reason to suppose that it breeds in the fur 
countries, and near the great lakes; those which
