So, literally, a few minutes before that, I downloaded this scientific paper about calculations on avian defecation, which is really quite interesting, because it turns out you can model this as something called "Poiseuille flow," and you can learn an awful lot about the physics of the avian rectum.
Que es realmente interesante, porque resulta que esto se configura como algo llamado "flujo de Poiseuille", y se puede aprender muchísimo sobre la física del recto aviar.
