Hybrids between Indian peafowl and Green peafowl are called Spaldings, after the first person to successfully hybridise them, Keith Spalding.[citation needed] Spaldings with a high-green phenotype do much better in cold temperatures than the cold-intolerant green peafowl while still looking like their green parents. Plumage varies between individual spaldings, with some looking far more like green peafowl and some looking far more like blue peafowl, though most visually carry traits of both.
