Folivory and Flight
It has been observed that folivory is extremely rare among flying animals. Morton (1978) attributed this to the fact that leaves are heavy, slow to digest, and contain little energy relative to other foods. The Hoatzin is an example of a flighted, folivorous bird.
Some bats are partially folivorous; their method of deriving nourishment from leaves, according to Lowry (1989), is to chew up the leaves, swallowing the sap and spitting out the remainder.

Famous quotes containing the word flight:
“What a cunning mixture of sentiment, pity, tenderness, irony surrounds adolescence, what knowing watchfulness! Young birds on their first flight are hardly so hovered around.”
