Both are reptiles but lizards are not dinosaurs, as dinosaurs have their legs under their body (like birds) and other reptiles (like lizards) have them at their sides.
Birds are not reptiles. They are different taxonomic classes and have significant differences in physiology and genetics.
Birds are warm blooded, reptiles are cold blooded.
Birds have feathers and skin, reptiles have scales.
Birds have two wings and two legs, reptiles have four legs.
Birds are phylogenetically reptiles and taxonomically not reptiles. Physical differences don’t change that they evolved from diapsids. Phylogenetically, we’re all just fish though
