Red-vented bulbul

Only man (and other primates), guinea-pigs, the Indian fruit bat and the red-vented bulbul (a bird) get scurvy other animals are able to synthesise ascorbic acid for themselves. 

Roy and Guha (R24) induced experimental scurvy in a bird, the red-vented bulbul Pycrorotus cafer). The birds lost weight and feathers and died after 16 to 45 days on a scorbutigenic ration. The scorbutic birds recovered with administration of ascorbic acid. The susceptibility to scurvy correlated well with the lack of activity in this species of the specific liver enzyme which is indispensable for ascorbic acid biosynthesis (L-gulonolactone oxidase). This enzyme was present in the liver of bank-myna Acridotheres ginginmanus) which was not susceptible to scurvy. 

Ascorbic acid differs from the other vitamins in that it is required in the diet by only a few species of animals—man, other primates, the guinea pig, an Indian fruit-eating bat, and the red-vented bulbul and some related species of Pas-seriform birds. Other species of animals synthesize ascorbic acid. All mammals and other larger animals require vitamin A, thiamine, riboflavin, nicotinic acid, and pyridoxine as essential nutrients, although microoi anisms usually have the power to synthesize all or most of these substances. 

For references, see Stone (1965). The only other vertebrates known to require exogenous ascorbic acid are the red-vented bulbul, Pycnonotus cafer, and related passeriform birds.
