Jay is a common name for several species of medium sized, usually colorful and noisy passerine or perching birds in the family Corvidae, or crow family, closely allied to the magpies (the names 'jay' and 'magpie' are to a certain extent interchangeable, not reflecting any genuine genetic difference between the two groups).See classification box for relevant genera links.
