几种鸟类合成L-抗坏血酸的能力与它们的生殖能力有关。在更原始的物种中，L-抗坏血酸的合成发生在肾脏中。在高度进化的雀形目物种中，肾脏和肝脏可以合成L-抗坏血酸，而在其他物种中，合成发生在肝脏中。在另外一些情况下，合成L-抗坏血酸的能力明显丧失。因此，鸟类抗坏血酸途径的进化模式与哺乳动物相似。
The ability of several species of birds to synthesize L-ascorbic acid is correlated with their phylogeny. In the more primitive species, synthesis of L-ascorbic acid occurs in the kidney. Among the highly evolved passeriform species, kidney and liver can synthesize L-ascorbic acid in some, whereas in others synthesis occurs in the liver. In still others, the capacity for the synthesis of L-ascorbic acid is apparently lost. The pattern of evolution of the ascorbic acid pathway among birds is thus similar to that among mammals.
