Ravenclaw

Ravenclaw values intelligence, creativity, wit, and wisdom."Wit beyond measure is man's greatest treasure" is an oft-repeated Ravenclaw proverb.[HP5][HP7] The house mascot is an eagle, the house colours are blue and bronze (changed to blue and silver in the movies). According to Rowling, Ravenclaw corresponds roughly to the element of air.
Rowena Ravenclaw herself is described as being beautiful in life, a trait which has, apparently, become common in her house. Attractive (and with their Ravenclaw wit and cleverness, sometimes idealistic) people seem to be plentiful in Ravenclaw, with Cho Chang described as 'extremely pretty', and Padma Patil (along with her twin sister, Gryffindor student Parvati Patil) is spoken of as the best-looking girl in the year, by Dean Thomas.
The dormitories are located in Ravenclaw Tower on the west side of the school. The common room, which went undescribed in the series until the climax of Deathly Hallows, is round and filled with blue hangings and fat armchairs, has a domed ceiling painted with stars, and also features a statue of Rowena Ravenclaw wearing her diadem. Harry also notes that, by day, the Ravenclaws 'would have a spectacular view of the surrounding mountains'. A logical riddle must be solved in order to gain entry, whereas the Gryffindor, Hufflepuff and Slytherin common rooms only require a password.
