Its not a bird, but its very similar to one. It does lay eggs, but that's hair not feathers and that's a snout not a beak. Actually they could almost be considered a type of dragon. These critters, which haven't been bestowed with a name quite yet, live in the frozen world I'm creating in my imaginary imaginings . . . they can run on their toes, as picture here, or have their feet flat so as not sink in the snow. They are generally herbivores, but won't pass up an easy meal if its not plants. The people in this frozen world have domesticated these critters and use them for transportation of all sorts.
