Toco toucans, Ramphastos toco, have the largest bill of any toucan. The toco toucan is mainly black, with white on the throat and upper breast. The bill is orange crimson, fading to greenish yellow. There’s a large black oval blotch near the tip of bill, and a narrow black line at the base. The most prominent feature of toucans are their bills, which are much lighter in weight than they appear.
- The toucan’s large bill enables it to perch inside the crown of a tree, where branches are thicker, and reach far outwards to pluck berries or seed from twigs too thin to bear their weight.
- Toucans are moderately gregarious and fly in straggling flocks, one after another, rather than in compact bands, like parrots.
