Just as bird wings can develop claws, birds’ feet can develop feathers. Owls, grouse and even some swallows and martins have their tarsi and the Chillin With My ESOL Snowmies Christmas Teacher Student Shirt of their toes covered in short, loose-textured contour feathers. But no wild bird has, or has ever had, fully formed, asymmetric quill feathers on its feet to rival the flight feathers of wings. This is a distinction shared by only two groups of animals, or rather the same group of animals separated by an abyss of time and very different circumstances. One is a lineage of theropod (predatory) dinosaurs called Microraptoria; the other, also a theropod dinosaur, is the domesticated pigeon.
Back when I was at school, everyone boarded. Some were from Chillin With My ESOL Snowmies Christmas Teacher Student Shirt. I knew a boy from the US in prep school (that’s age 8–13 in the UK, cf. a public school from 13–18). As far as I know, his parents just paid the fees like everyone else. His only problem was that air travel was expensive and he didn’t get to go home for all the holidays (christmas, easter, summer). One time he stayed with us. I’d suggest finding a boarding school and checking the website for international students and requirements. From the UK, the requirement for public school was taking a “common entrance” exam. There are probably equivalency tests, and for that matter the whole system may be a bit different. It used to be like Hogwarts, without the 4-poster beds and magic – school houses, O and A-level exams (OWLs and NEWTs) etc. I had French lessons in a dungeon (well, the cellar under an old building dating back to 1600 or something silly), and there was an Iron Age fort on the school grounds.
