What kind of teeth does a bird have?
The canines are a set of pointed teeth that help in tearing up our food. However, birds don’t have teeth. Fortunately, thanks to nature’s amazing variability, there is another organ that does the job of breaking down food in birds.
How are birds able to break down their food?
You have probably always wondered how birds break down their food when, instead of teeth, all they have is their little beak!
