These are photos of a Hybrid Canary.  These birds are bred by crossing a Green Singer Finch with a Canary. This is called a Hybrid and not a 'Mule' because the genes of the Green Singer Finch and Canary are very close.   Therefore, it produces a bird that can be breed in the future. Unlike a 'mule' which can not reproduce.  These birds are amazing singers.  If you are looking for a real singing bird with lots of song, then you want to try one of these guys.
