How much weight can a Macaw's tongue lift?

I am curious about this because in this RPG I am reading, Macaws are assigned a Strength stat of 3, and their tongue is treated like an arm, so they can lift 1.8 pounds in 1 second and 3.6 pounds in 2 seconds.

I am curious what people with Macaws have observed with them manipulating objects and lifting them, how heavy you have seen them lift.

Does that seem too strong? Too weak? If anyone has seen them lift anything heavier, it's possible to exceed that using special 'lifting' skill and 'extra effort' rules.

I've seen human world records at 24-27 pounds, accomplished via piercings since our tongues can't actually grab stuff. No idea what normal people could accomplish, I think even 3 pounds could be pretty uncomfortable personally!

I'm not sure that you will find any imperial knowledge within the Companion Parrot Community. Or, what functional use it will provide.

What weight a MAC or any Parrot can lift with just its Beck, let alone its Tongue is rarely a notable event. Most individuals have greater interest in what their Parrot's can crush, crack-open and/or chew-away.

If we are watching, its what, in combination with their Beck, Neck, Chest, and Legs that they can carry-away or drag-up on to any number of elevated surfaces.
