Red fody forest clearings, grasslands and cultivated areas, but not in dense forest. In Madagascar it is regarded as a pest of rice cultivation. It has been introduced to other areas of the Indian Ocean, included the Amirantes, Comoros, Seychelles, Mauritius and Réunion. The red fody feeds largely on seeds, especially grass seeds, and insects, but several other foodstuffs are also taken; these include fruit, nectar, household scraps and copra. Outside the breeding season, this bird is gregarious. As the breeding season approaches, males establish territories, about in diameter. The birds are monogamous, and the male starts building the nest in the

Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his "Systema Naturae" for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the red fody. Linnaeus included a brief description, coined the binomial name "Loxia madagascariensis" and cited Brisson's work. This species is now placed in the genus "Foudia" that was introduced by the German naturalist Ludwig Reichenbach in 1850. The type species was subsequently
