I'm surprised how I never been able to found an online translation of "cocotte en papier" (which is the thing pictured below), or people able to answer IRL, other than via less precise terms as "origami" or "paper bird".
"Paper bird" is too un-specific (see link below) compared to the original. E.g. I know 3 types of cranes, and there are yet other origami birds, than the "hen/cocotte" (that is supposed to be famous for being one on the most easy and well-known origami after the plane ;-) , at least in France ). https://www.google.com/search?q=paper+bird&tbm=isch
Searching "paper bird" from my French account, the cocotte appears only once on this search, at rank ~35, and not again in the several hundreds following. I didn't suspected such a peculiar folding and concept could be idiomatic! Like, all French children know how to fold it, for generations and up to now, and it's not by school teaching.
--> Is there a name for that thing ?
(NB: in French "cocotte" is a colloquial term for hen, but maybe other countries' people see another kind of bird in this origami :-) ).
Note that this very origami figure used to be the typical illustration for procrastination in France; I don't know if it carries the same connotation in other countries.
