Reptiles need their outside environment to maintain their body temperature, which makes them ectothermic. Birds, on the other hand, regulate their own body temperature, making them endothermic.

the prefixes tell you: "ecto-" means (approximately) "outer", while "endo-" means (approximately) "inner". Ectotherms have their body temperature modified by outside influences, while Endotherms have their body temperature modified by internal influences (within themselves). Ectotherms are sometimes called "cold-blooded"; Endotherms, sometimes called "hot-blooded"
