carotenoid-dependent plumage

The Red Factor Canary is a unique variety whose vibrant red plumage depends on specialized dietary carotenoids during molting. Available in base (yellow) and bleach (white) varieties, these birds require color-feeding protocols to develop and maintain their signature hue. While moderately more demanding than standard canaries, they offer fascinating insights into avian nutrition and genetics. Ideal for experienced keepers, Red Factors demonstrate how diet directly influences feather pigmentation, creating living examples of avicultural science.
