Thanks for the tip. You know what? One of my cousins used to have a beautiful canary. The canary would fly around the glass-encased balcony while my cousin was cleaning up the cage, according to my cousin. And my cousin didn't have to "beseech" the bird to return to the cage because the bird would fly back to the cage afterwards.
Regretfully, her hubby forgot to feed the bird while my cousin was away for a few days. Accordingly, the starving bird flied to another world to sing with Sinatra.
