Falconiformes typically have a sharply hooked beak with a cere (soft mass) on the proximodorsal surface, housing the nostrils. Their wings are long and fairly broad, suitable for soaring flight, with the outer 4–6 primaries emarginated. Falconiformes have strong legs and feet with raptorial claws and an opposable hind claw. Almost all Falconiformes are carnivorous, hunting by sight during the day or at twilight. They are exceptionally long-lived, and most have low reproductive rates. Falconiformes are among the most diverse orders in size. The smallest species is believed to be the Black-thighed Falconet, small males of which can weigh only 28 g (1 oz), measure 14 cm (5.5 inches) and have a wingspan of 26 cm (10.3 inches). The largest species is the Cinereous Vulture, at up to 14 kg (31 lbs), 118 cm (46 inches) and 3 m (10 feet) across the wings.
