Nevin had watched the avian enter, her body posture slumped over, taking in the droop and the way she slouched even as she sat down. He had studied her for a few moments before humming to himself as he pushed his food and drink to one side of the table. A few moments of searching - and a hush falling over the room which made him pause for a second - and he had found what he was looking for.

Parchment and a quill, with an ink bottle - writing tools, always a good idea to keep on hand. He shot a quick glance back at the humanoid bird, taking in the fact that they were able to consume human-standard foods and began jotting notes down on the parchment, the sound of the quill tip scratching into the paper strangely loud in the hushed quiet of the Tavern following the new arrival.

"Avian in nature, potential for increased metabolism, possible lower body mass than traditionally ground-based individual. Likely needs a lower dosage as compared to the norm - though perhaps not.
Still, lower dosage to begin with would probably be wise, if needed quantities can be increased to satiate needs from there." This was said quietly, to himself as Nevin wrote. He didn't even seem to note that he was speaking, and if someone looked at the parchment he was writing on they would find that his words did not match up - the page was slowly being filled with formula.
