The waxwingBombycilla garrulus as a frugivorous feeding specialist

Summary

Eight waxwings,Bombycilla garrulus, were fed exclusively with vegetable food for periods of 10–18 days. In contrast to other song birds, they maintained or increased body weight during that time, or reduced it only moderately. Thus the waxwing is a feeding specialist which can subsist at least temporarily on a totally vegetable diet.
