- ‘Falconids are medium-sized to large birds of prey (wingspan 55 to more than 125 cm, weight 28 to 2100 g), typically with hooked beaks, large brown eyes and a yellow cere, eyerings and feet.’
- ‘Exposed skin of the ceres, dewlaps, horns, bills or legs may be brightly colored red or blue.’
- ‘For both species, body size traits (in mm) included mean tarsus length, mean flattened wing chord, tail length, and culmen length (base of cere to tip of beak).’
- ‘The falconids resemble the accipitrids in some characteristics, such as a powerful hooked bill, a fleshy cere straddling the bill, heavy bony brow ridges, and a crop (to store freshly eaten food).’
- ‘They have large dark eyes and yellow to orange legs, cere, and eye-rings.’
Late 15th century: from Latin cera ‘wax’.
