The Asian Songbird Situation Grows

The Asian pet dog bird trade spells problems for many varieties, and also if it’s not the birds’ excellent appearances that put them in danger, it’s their beautiful singing voice. Besides their popularity as pet dogs, they are extremely sought after as entrants in bird track competitors.
