PARROT
Beaks
They have a short, robust beak that ends in a conical shape, allowing them to break open seeds.
The function of the parrot beak is for climbing, as well as manipulating and crushing objects.
Bills
Made up of a hard protein shell of keratin, it covers the bony jaws (the upper-maxilla and lower-mandible). The upper bill is called the rhinotheca, and the lower bill is called the gnathotheca
HUMMINGBIRD
Beaks
A hummingbird's beak is generally shaped like any other bird beak, just longer in proportion to its body. The edges of the hummingbird's top beak will overlap the edges of the hummingbird's bottom beak. A hummingbird's bottom beak is slightly flexible. Hummingbirds do not drink though their beaks like a straw.
Bill
A hummingbird's long, curved bill (or beak) is perfectly designed to sip the nectar deep inside trumpet-shaped flowers.
