Minecraft Parrot glitches out whilst looking at the top left 3d character model while crouching

While crouching while having a parrot sit on your shoulder, there is another view of the player that shows up in the top left corner of the screen.  When a parrot is on your shoulder, the parrot model continues spazzing out in this second view, and it gets faster when the player looks down. Only a visual bug though it seems.
