Numerous possibilities, wheel bearing, brakes, belts, etc.
a parrot makes a screech noise
it could be your tires on the pavement.
What causes a car to screech is when you get too excited to go fast you step on the gas pedal or in other words you floor it! This causes the tires to regain grip on the ground and makes the screech noise.
Depending on the species, a parrot that is upset will chatter, squawk or screech loudly.
This be a wide range of things does it make the noise when the vehicle is in park and you rev up the engine ? It could be a heat shield on the exhaust system. it does not make the noise if it is just idling....but if you press the gas it makes a noise and when ur driving it makes noise. But I had to put a flang where the header conects to the exaust cuz it was leaking and i thought that was where the noise was comin from but its still makin the noise.
Could be a wheel bearing/hub going bad.
