A study found that crows that live in suburban areas, where they have access to fast food scraps, suffer from high bad cholesterol... Now, crows are omnivorous and that means that their natural diet has bad cholesterol - which, in turn, means that nature gave them a way of getting rid of it IF the intake is at a normal level (same as humans) but parrots, being herbivores, are not supposed to ever consume any food with bad cholesterol so think about this next time you are tempted to feed your parrot human food!
