Parrots sitting on shoulders don't drown in water or burn in lava / Parrots shouldn't go diving

As the parrots "become a part of the player" which means they got no own hitbox when they sit on the player's shoulder and can't be effected also by any potions, please consider to either:

1. have them "overtake" the player's remaining air, be it those affecting the player via potion effects (Water Breathing) and/or enchant (Respiration) or

2. if the player applied a throwable potion (e.g. Water Breathing or Fire Resistance) to the parrots before putting them on the shoulder, please have also a timer for the parrots, for the applied potion effects, which would consequently mean though, as they would be treated separately, that they should appear in the player's vision/GUI as well.

Personally, I'd prefer the first solution, considering they are no separate entities from the player anymore if on the shoulder/ShoulderEntity.

Another solution would be that they "pop off" the player's shoulder when entering water deeper than e.g. 2 blocks and swim up/don't drown.

The question would be also, as long as the parrots are ShoulderEntities, what happens if the player gets attacked by hostiles or other players? Do the parrots also get damaged whilst sitting on the player's shoulder or not?

Consequently, and considering their very low health, they shouldn't get any damage as ShoulderEntity. ( ? )

Edit: Another solution would be that they "pop off" the player as soon as the player experienced a knockback-effect, e.g. from the Thorns enchant or an attack or e.g. taking other damage like walking on Magma Blocks unprotected or not crouching or touching a Cactus etc..
