My jaw's stronger than the Caninde Macaw's

from Canibus – Master Thesis Lyrics on Rap Genius

Probably refers to the blue-throated macaw (ara glaucogularis, formerly ara caninde). It is native to South America and, like all big birds, can fuck you up with its beak. Humans have a bite force of around 150 psi on average, however, a large macaw can have a bite force of up to 500 psi, so he has a jaw over four times as strong as the average human.
