Well you already know the question. Something about Hippogriffs in general: rated XXX. They have the head, wings, forelegs of a giant eagle and body, hindlegs, tail of a horse. They are carnivores. Their wingspan is approx 24 feet (7-something meters), which makes me realise just how huge they are.
I was trying to think how someone would find Buckbeak (OotP) if they came upon him in Mrs Black's room at night time. Does he sleep standing? Also any ideas on how they actually managed to get him in Grimmauld Place with that huge wingspan of his.
