    Jays are related to crows and ravens (Corvid family), bluebirds are not. Needless to say they are 2 different species and in 2 different family of birds. To be honest I am more familiar with Jays then bluebirds. The wildlife rehab group that I am with takes in more Jays then Bluebirds due to the fact that Bluebirds are not a common resident where I am.

    First off they are in different families, blue jays ( http://www.birds.cornell.edu/AllAboutBirds/BirdGuide/Blue_Jay_dtl.html ) are in the corvid family and are related to crows, ravens and magpies.
    Bluebirds actually refers to several birds :
    the eastern bluebird,http://www.birds.cornell.edu/AllAboutBirds/BirdGuide/Eastern_Bluebird_dtl.html
    the western bluebird,http://www.birds.cornell.edu/AllAboutBirds/BirdGuide/Western_Bluebird_dtl.html
    the mountain bluebird, http://www.birds.cornell.edu/AllAboutBirds/BirdGuide/Mountain_Bluebird_dtl.html
    which are in the thrush family and so are actually related to robins.

    Other than the obvious physical differences, the size differences , the reddish chest in the western and eastern bluebirds, the blue chest on the mountain bluebird vs the grayish/blue gray chest of the jays, the crest on the blue jay and other such features these species have very different biologies.
    Bluebirds are cavity nesters whereas blue jays will just build it in a tree or a snag,
    Bluebirds they eat mainly insects and fruits (which is why they don’t show up at bird feeders) whereas blue jays have a more varied diet which includes; seeds, bird eggs, chicks, fruits,insects, nuts, etc.
    Bluebirds tend to be more migratory than jays and depending on which bluebird location is a factor as in the western side of the continent blue jays are replaced by Steller’s jay.
    Bluebirds tend to prefer open areas like golf courses and fields whereas the jay prefers wooded / semi-wooded areas

    Bluebirds are related to robins. Blue Jays are related to crows. I’m sure you’ll be able to find lots of information on both online.
