Nosebleeds, or to be more precise what do the other cogniscients think when it happens. Do they go for a medical kit and flutter about while the human sighs and holds their nose, or do they comment that at least the humans do something normally for once (but what scared them enough to defensively spout blood?) or something else entirely?
The human - the first they had met, was making an intermittent noise with its proboscis.
Snurf.
Communicating was spotty. Both sides only knew a few words of GalStand and the rest was pantomime. Interspersed, of course, with snurf.
Finally, the human dragged an arm across its face. Painting its limb with a vivid display of bright red blood. It muttered a human curse and pinched its proboscis shut while it fumbled for something to stopper it with.
The Temikai were perplexed, of course. They wondered for decades about what they had done to provoke a nurturing response from the human.
And they were understandably upset when they found out what it really was.
