The modern taxonomy of reptiles includes many more subdivisions and also should include the bird. For practical reasons we give a simplified version here.

     Tyrannosauridae                                                                  Family
    Aves - Birds
in a modern systematics you would find the birds in this place as for example the crocodiles are more closely related to the birds than to any other living reptile group.
But for the sake of a clearer arrangement and easier use we follow the common usage to treat the birds as a class of their own.
