    Biggest by mass, but a bird with the mass of a human cant fly (biomechanically impossible), so there needs to be magic fuckery involved.

    Meaning that a shapeshifter that turns in a flying bird with the same mass as a human would likely not be as large as you think. Humans are very dense compared to birds. Assuming we keep that density, we could be smaller than some of the larger eagles or carrion birds.

      The largest flying animal to ever live, as far as we know, was the Quetzalcoatlus, which is estimated to have a mass up to over 400 pounds. Thats more mass than 99% of all humans, flatly disproving your claim. Just because theres no living bird with that mass doesn’t in any way mean its biologically impossible.

      Why would you assume it would have the same density as a human? This is an arbitrary restriction you’re adding to the scenario. Conservation of mass doesn’t require conservation of volume.

        I love the quetzalcoatlus, it’s one of my favorite summons in D&D. 80ft fly speed, flyby, 10ft reach, 22 (6d6+2) damage with a flying charge, and only CR 2. 🤌

        If you assume that we can change density then its possible sure.

        Just because theres no living bird with that mass doesn’t in any way mean its biologically impossible.

        If you just reshaped a person into a bird shape, its biomechanically impossible for them to fly.

        Why would you assume it would have the same density as a human?

        Because otherwise you arent turning a person into a bird, you are just making a bird (or other flying mammal) with the same approximate mass as a human.

        This is an arbitrary restriction you’re adding to the scenario.

        Seems implied to me

        Conservation of mass doesn’t require conservation of volume.

        So the original post would just be “a flying bird with the same mass as a human would be a huge bird”

        Which…sure
