(Or at least partly factual, I don’t know if we’ve proved that they can’t read.)
- They can go a lifetime without water
Birds are experts in conserving water.
Along with mammals, they’re the only animals capable of concentrating urine, and this helps them reduce the water they need, thus reducing their weight and making flight a heck of a lot easier – even if they choose not to fly much.
These birds can go an entire lifetime without drinking water (technically, so can everything else, but at least in roadrunners that lifetime isn’t reduced by it), and get their moisture entirely from their diets.

Chuck Jones did the research!
Ok. Can they write? Can they understand the concept of written language enough to hold a sign like that for others to read? 😏
They don’t have to know what’s on the sign to hold the sign.
Checks out. Meep meep.
