Keel-billed Toucan
Ramphastos sulfuratus
Including its bill, the length of the keel-billed toucan ranges from around 42 to 55 cm (17 to 22 in), while its wing length typically ranges from 189.4 to 208.4 mm (7.46 to 8.20 in). The bird typically weighs about 380–500 g (13–18 oz). The large and brightly coloured bill averages around 12–15 cm (4.7–5.9 in), about one third of the bird's total length. The bill is mainly green with a red tip and orange sides. While the bill seems large and cumbersome, it is in fact a spongy, hollow bone covered in keratin, a very light and hard protein.

Yellow-throated Toucan
Ramphastos ambiguus
The yellow-throated toucan is 47 to 61 cm (19 to 24 in) long and weighs 584 to 746 g (1.3 to 1.6 lb). The three subspecies differ little in their dimensions, though females' bills are shorter than males' in all three. Bill lengths vary between 15.1 and 19.8 cm (5.9 and 7.8 in) in males and 12.9 and 16.0 cm (5.1 and 6.3 in) in females. Other measurements differ little by sex. Their wing chord is 20.4 to 24.8 cm (8.0 to 9.8 in), their tail length is 14.0 to 16.2 cm (5.5 to 6.4 in), and their tarsus is 4.7 to 5.5 cm (1.9 to 2.2 in) long.
