The Field Egg Group (Japanese: 陸上グループ Land Group), known prior to Pokémon Diamond and Pearl as the Ground Egg Group, is one of the fifteen Egg Groups. As of Generation VIII, 244 Pokémon belong to this group, making it the largest Egg Group.
Pokémon in the Field Egg Group tend to be terrestrial creatures. Most are based on mammals though there are several exceptions, such as Ekans, Kecleon, and Sandile, which are reptiles, and Delibird, Torchic, and Piplup which are birds.
With the inclusion of Smeargle, a Pokémon capable of learning almost every move in the game, this group has the most versatility in terms of bred movesets, unhindered by the need of chain breeding.
